Added a simply system to keep record of the x most recently played
OpenALSoundS (where x is the number of simulataneous sources allowed) and,
in case a new sound refuses to play, stop()'s the least recently played
sound and attempts to play it again (but only once, to prevent endless
loops in case something else prevents the sound from playing).
Added removal of disposed sounds from the buffer
Fixes issue 912

Android Audio now functions correctly on pre-Android 4.1 (pre-Jellybean)
Minor formatting
Remove comments on issue number
Add support to GWT for GlGetInteger, glGetFloat and glGetString
Correct packing for square texture (previous code would increase the
size of the image after packing. the new one packs to square image
directly, giving better result).
AndroidSounds now respond to lifecycle

Fixes #1263 on Android
Behavior is now alike with music on Android
Updated GWT backend to GWT 2.6.0

- Java 7 support (yay!)
- IE 6/7 support disabled by default.

Merge remote-tracking branch 'origin/master' into gwt-2.6.0
Updated Changes to reflect gwt upgrades.
Added gradle support for running texturePacker at build time.

Make sure the proper ext.texturePacker parameter is set in the toplevel
gradle.build file and have TexturePacker run with those whenever the
"texturePacker" task gets invoked, e.g. "./gradlew texturePacker
desktop:run".
