Sound class added. Make it possible to play the same sound multiple times simoultaneously
All sound effects (not music) are now loaded directly into a Sound-object
The maximum number of simoultaneous playbacks of the same sound can be set with the engine option: cachedSoundCopies (as the name implies, setting a low number should use less memory)
New engine option added: avoidSubPixelRendering
The new option makes the engine round sprite and textblock positions for drawing them.
Enabling avoidSubPixelRendering has almost no impact on chrome, but speeds up firefox performance, especially for text rendering.
The engines will by default enable the option for firefox and IE, but disable it for webkit-based browsers.
Minor refactoring of the host environment detection code
