GrandPerspective 1.0

What's new in this version:

New functionality:
- Added a customizable toolbar, including new controls: added control for changing the focus (which previously could only be done using the keyboard or scrollwheel) and added new "Open with Finder" action (not to be confused with existing "Reveal in Finder" action).

Minor improvements:
- Improvements to the appearance of the view window: moved info about selected item to statusbar, removed borders around view, not showing rectangle around outermost item in the selected path unless necessary.
- Positioning newly opened view windows so they cascade.
- When creating a derived view window its size matches that of the original window.
- Sorted the available tests in the "Edit Filter" window by name.
- Sibling directories are scanned depending on their creation date (oldest first). This deterministic ordering is particularly helpful when scanning an entire TimeMachine backup as hard-linked files  will be included in the backup where they first appeared.
- Made selection automatically stick to end-point when reaching a file after moving selection down a level.
- When resizing the window the view is still being shown.
- Added keyboard shortcuts for zooming.
- Added menu item for visiting the GrandPerspective website.
- The selection only follows the mouse when the view window has main status.
- Now also setting hardlink and package status for root of scan tree.
- Showing an alert when an invalid date value is encountered when loading scan data.
- Alerts created by a view window are now all shown as sheets of that window.
- Moved horizontal drawers away from the window's left edge.
- The initial size of windows and the color gradient for drawing rectangles in the view are now taken from the user defaults.
- Moved description of file type in Focus panel from separate text field to tooltip of the file type identifier.

Bug fixes:
- Included workaround for bug #2243134 (crash while scanning NTFS mounted filesystem).
- Coloring by Level would end up in endless loop for packages at level zero when package contents were hidden. Not anymore.
- Aborting a drawing task that was just about to complete could result in premature aborting of next task. Not anymore.
- Closed Edit Mask windows would reappear when the application got activated again after reactivation. They now remain hidden.

Code clean-up:
- Renamed FileItem -isSpecial to -isPhysical (and inverted meaning)
- Simplified abortion of background tasks (removed enabled state from TaskExecutor).
- Moved zoom and focus functionality to DirectoryView.
