This fixes a typo that left the "Redo" command with the wrong key shortcut on Windows in the last release, adds updated reference, and includes a handful of other smaller fixes.

Fixes:

• "Redo" key shortcut for Windows screwed up
• Fix an editor problem with plain text (css, etc) files
• Default to using java.awt.Desktop methods for URLs/files when available on Linux. Also cover a few weird cases that were failing silently.
• Ignore .class files found in the META-INF folder for imported JARs
• Get rid of errant 'Could not parse -1 for display' message.
• Fix up and clean a few file i/o issues that were causing resource leaks with loadXxxx() commands, and intermediate folders not being created for temporary files used by the saveXxxx() commands.

Additions:

• Added reference for circle(), square(), push(), pop()

Contributions:

• Updated translation of the word "sketch" for Russian speakers
• Update missing @Deprecated tags in PApplet.java
