* cache text vertex for StaticText, AnimatedText and Creature names
* improved outfit rendering
* fully compatible with OpenGL 1.1
* enable mipmaping for game sprites again
* Ctrl+W hotkey clean game texts
* fix battle rendering
* fix rendering glitch when following creatures
* properly throw exceptions from C++ to lua and avoid exception crashs
* fixes rendering states in framebuffer
* the rendering now consits of two panes
- the background pane (for animated stuff like the map)
- the foreground pane (for steady stuff, like UI)
each pane has it own max FPS and works idependently
this may increase graphics performance on many platforms
* option to pass -opengl1 or -opengl2 as argument
* note that with this commit there are a lot of graphics regressions and the master will remaing unstable for a while
* shaders disabled for a while
