Fixing technical issues

Currently working on ironing out nVidia related shader issues. Like... Depth of Field precision issues came into picture. Solved. Next thing is : light is flickering on the terrain with nVidia cards. Another fatal error with character creation is fixed. After fixing these i'll roll out another release this time with bigger publicity. Thanks for all the folks who helped to discover the problems with the new release! (especially: qubodup, tidbit, people at Hungarian Unix Portal.)

And yeah, happy 3rd birthday jClassicRPG. :D
