Darktable 2.2.0

What's new in this version:

- Add new automatic perspective correction module
- Liquify tool for all your fancy pixel moving
- A new image module to use a Color Look Up Table (CLUT) to change colors in the image
- In Highlight reconstruction module, the mode LCh reconstruction was completely rewritten, and is no longer useless!
- A new tool, darktable-chart, that goes along with the CLUT module, to create styles for the latter
- Exposure fusion in the basecurve module to lower the dynamic range of images
- Add new raw overexposure indication
- Darkroom: the preview (in top-left corner) is now no longer pre-demosaiced (but just downscaled without demosaicing it at the same time), thus the preview, color picker, histogram show the proper results, especially when there is highlight clipping.

Quite Interesting Changes:
- Split the database into a library containing images and a general one with styles, presets and tags. That allows having access to those when for example running with a :memory: library
- Support running on platforms other than x86 (64bit little-endian, currently ARM64 only)
- darktable is now happy to use smaller stack sizes (no less than 256Kb). That should allow using musl libc
- Allow darktable-cli to work on directories
- Allow to import/export tags from Lightroom keyword files
- Allow using modifier keys to modify the step for sliders and curves. Defaults: Ctrl - x0.1; Shift - x10
- Allow using the [keyboard] cursor keys to interact with sliders, comboboxes and curves; modifiers apply too
- Support presets in "more modules" so you can quickly switch between your favorite sets of modules shown in the GUI
- Add range operator and date compare to the collection module
- Add basic undo/redo support for the darkroom (masks are not accounted !)
- Support the Exif date and time when importing photos from camera
- Input color profile module, when profile is just matrix (and linear curve), is 1/3 faster now
- Rudimentary CYGM and RGBE color filter array support
- Nicer web gallery exporter -- now touch friendly
- OpenCL implementation of VNG/VNG4 demosaicing methods
- OpenCL implementation of Markesteijn demosaicing method for X-Trans sensors
- Filter-out some useless EXIF tags when exporting, helps keep EXIF size under ~64Kb
- OpenCL: properly discard CPU-based OpenCL devices. Fixes crashes on startup with some partially-working OpenCL implementations like pocl.
- darktable-cli: do not even try to open display, we don't need it
- Hotpixels module: make it actually work for X-Trans
- Cmstest tool should now produce correct output in more cases, especially in multi-monitor setups.
- Darkroom histogram now uses more bins: use all 8-bit of the output, not just 6

Some More Changes, Probably Not Complete:
- Drop darktable-viewer tool in favor of slideshow view
- Remove gnome keyring password backend, use libsecret instead
- When using libsecret to store passwords then put them into the correct collection
- Hint via window manager when import/export is done
- Quick tagging searches anywhere, not just at the start of tags
- The sidecar XMP schema for history entries is now more consistent and less error prone
- Rawspeed: fixes for building with libjpeg (as opposed to libjpeg-turbo)
- Give the choice of equidistant and proportional feathering when using elliptical masks (shift+click)
- Add geolocation to watermark variables
- Fix some crashes with missing configured ICC profiles
- Support greyscale color profiles
- Lens correction module: switched back to normal Lensfun search mode for lens lookups
- Make sure that proper signal handlers are still set after GM initialization
- OSX: add trash support (thanks to Michael Kefeder for initial patch)
- Attach Xmp data to EXR files
- Several fixes for HighDPI displays
- Use Pango for text layout, thus supporting RTL languages
- Feathering size in some mask shapes can be set with shift+scroll
- Many bugs got fixed and some memory leaks plugged
- The usermanual was updated to reflect the changes in the 2.2 series
- Tone curve: mode "automatic in XYZ" mode for "scale chroma"
- Some compilation fixes

Lua specific changes:
- All asynchronous calls have been rewritten
- the darktable-specific implementation of yield was removed
- darktable.control.execute allows to execute some shell commands without blocking Lua
- darktable.control.read allows to wait for a file to be readable without blocking Lua
- darktable.control.sleep allows to pause the Lua execution without blocking other Lua threads
- darktable.gui.libs.metadata_view.register_info allows to add new field to the metadata widget in the darkroom view
- The TextView widget can now be created in Lua, allowing input of large chunks of text
- It is now possible to use a custom widget in the Lua preference window to configure a preference
- It is now possible to set the precision and step on slider widgets

Changed Dependencies:
- CMake 3.0 is now required
- In order to compile darktable you now need at least gcc-4.7+/clang-3.3+, but better use gcc-5.0+
- Drop support for OS X 10.6
- Bump required libexiv2 version up to 0.24
- Bump GTK+ requirement to gtk-3.14. (because even debian stable has it)
- Bump GLib requirement to glib-2.40.
- Port to OpenJPEG2
- SDL is no longer needed
- Remove gnome keyring password backend
- Usermanual has been updated, and will be released shortly after
