Processing 3.2

What's new in this version:

- This release includes a handful of fixes to deal with startup bugs, plus several internal changes for how Modes are implemented.
- For those semantic versioning enthusiasts keeping track at home, the version has been bumped from 3.1.x to 3.2.x to denote the internal API changes.

Bug Fixes:
- Processing .jar files in CLASSPATH can cause startup crash
- Remove java.ext.dirs on startup to avoid conflicts and startup errors
- Add 2016 to the About screen.
- Write preferences.txt using a temporary file (and save the previous version as preferences.old)
- Some Table cleanup based on other CSV parsing work
- Can't render PGraphics object using image() within a PDF

Contributed Fixes:
- Use HTML to print (a contributed fix for a handful of printing issues)
- NullPointerException in SketchCode.getDocumentText()
- Error checker now adds 'public' to all default access methods
- Fix resizing targets for async save
- Make loadStrings() and loadJSONObject/loadJSONArray() error msgs consistent

Changes:
- Implement template sketches
- PApplet.main(Blah.class) now works (for easy refactoring)
- Rewrite Util.listFiles() because it wasn't working properly
- Add printStackTrace() method in PApplet that can be overridden

Depeche Modes:
- Add template support for Modes
- Added getSketchbookTemplatesFolder() to Base
- Move general PDE code out of JavaMode and into general base classes
- Change default PdeInputHandler constructor slightly (added another copy so that older Modes will still work properly)
- Change PdeKeywords to PdeTokenMarker (please notify us if this breaks anything)
- Added Mode.requireExampleCompatibility() so that Modes can specify whether example packages should specifically mention their Mode in order to be visible when that Mode is in use.
- Mode.getTokenMarker(SketchCode code) passes through to no arg version if not overridden.

Input method work from Tsuyoshi Fukuda (tyfkda):
- Enable input method support by default on Japanese/Korean/Chinese systems
- Set text color for InputMethod
- Set sketch as modified when any character committed using input method
- Insert characters by InputMethod at one time
- Insert string when it is committed
- Simplify conditional branch
