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).

better error handling of null style argument for TextButton
Merge pull request #1266 from jrenner/textbutton

better error handling of null style argument for TextButton
Fix decoding of layer data.

InflaterInputStream uses a buffer during read. When it gets to the end of
the buffered data during a bulk read, it will not buffer more data until
the next read, so it is not guaranteed that the full 4 bytes will be read
in one read operation. Attempt to read more bytes until we get our 4
bytes, or until we hit the end of the stream.
Better equals.
who fucked up Texture#delete? :p
made Decal constructor public again, because GWT explodes otherwise
