Processing 3.1.2

What's new in this version:

PDE FIXES:
- NullPointerException in LanguageBundle.read() on startup that prevented Processing from starting up on Windows machines. Network drive issue.
- Bring back preference to hide the error checking. Error checking will continue in the background because it's needed for parsing/preprocessing, but some were complaining about the error checker messages.
- Updates to Japanese translation
- Make preferences button wider for Japanese
- Fix logic for warning message when the Mode cannot be changed
- Update to Java 8u102 build 14

API FIXES:
- Rewrite CSV handling to take care of some parsing bugs and improve performance. Note that the 'newlines' option is no longer necessary when loading files that contain newline characters mid-field.
- Prevent random(low, high) from returning 'high'
- Fixed iterator remove() methods so they don't skip container elements
- Added a check for length 0 arrays in expand()

GRAPHICS:
- Disable asynchronous saveFrame() by default. This can really improve performance, but can cause weird glitches. Bring it back by using hint(ENABLE_ASYNC_SAVEFRAME) in your code to blissfully and speedily create image sequences. https://github.com/processing/processing/issues/4578
- Prevent NPE in loadImage() when called before setup()
- Fix crash when calling getUniformLoc() called in PShader.set()

RASPBERRY PI:
- IO: Fix drawing for SPIAnalogDigital examples h
- Update JVM warning text on Linux
- Undo the 8u91 workaround, add Mesa warning for ARM
- IO: We want motors, they said (implements SoftwareServo)
- Add a temporary workaround for the CHIP to deal with cursor problems
- Fix GLExceptions on Raspberry Pi when using offscreen PGraphics

FIXED EARLIER:
- Debugger deadlocks when choosing "Step Into" on println()
- Suggestions switch scope to first import
- loadImage() immediately after saveFrame() foiled by async default
- the hint() mostly works, but gross to use a hint frequently
- Fix the Downloader so that builds work again
