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

GWT Backend: fixed generated getter/setter for primitive fields
This fixes the problem described in PR #1005 by strongly typing the generated getters/setters:

// com.badlogic.gdx.math.Vector2#x
private native float g1866(com.badlogic.gdx.math.Vector2 obj) /*-{return obj.@com.badlogic.gdx.math.Vector2::x;}-*/;
private native void s1865(com.badlogic.gdx.math.Vector2 obj, float value)  /*-{obj.@com.badlogic.gdx.math.Vector2::x = value;}-*/;
