COMPLETE REWRITTEN IN OOP / CODE SWAP

This is a first release of complete new rewritten source of CSWP. Not
all features implemented yet. Its a first version which has been wrote
until nearly same state as old version before. Is written in OOP now!

Thunderstorms, sounds, and some weather improvements not implemented
yet.

Serverside is very basic and only for testing purpose at the moment.

"F2" opens new debug panel to have a look onto all needed stats.
"F3" opens new coded shader panel (most shaders customizable now)
(unfinished but works)

Hope we can start with this version to get new results in next week.
Performance should be a lot better.

Some shaders were reworked too:
-- new water effects
-- godrays reworked
-- image quality shader added
-- vehicle shader reworked
-- glass improvements

Thanks for your patience and sorry for maybe unusable work based on old
version now. Please use this state as new reference!

Best wishes, Sam@ke
