RTFSS 1.1 released!!

This is one of the most important releases of RTFSS to date since the initial Sourceforge Release.

The most important features are:

*Support for viscoelastic fluid

*"Pool demo" (with raytraced refractions and caustics computed entirely on GPU)

*3d audio engine (based on OpenAL 1.0) and added a background sound (tested to work with 5.1 speakers..) [3d audio only shows on pool demo when adding drops with 'g' key]

*Multisampling support.

*Screenschoot grabing

please see changelog and release notes in release 1.1

It contains some bug fixes and finally contains ( I hope ) all the required libraries.
