Fixed TRLE colors and SDL heading

ChangeLog.md

     [ 20140615 ]
     * Added FontManager, selecting Font library to use depending on
       the file extension of the font file specified in the config.
+    * Fixed menu heading not visible when using FontSDL
+    * Font::drawText now only implemented in Font
+    * TRLE Fonts can now be properly colored
 
     [ 20140614 ]
     * Implemented TRLE Font loader

TODO.md

 * Support SSE with other compilers than Clang (src/CMakeLists.txt)
 * Visual C++ compiler flags? (CMakeLists.txt)
 
-## Bugs
-
-* Menu Header “OpenRaider” not visible when using FontSDL?
-
 ## Future Features
 
 * Use only assets from old TR games, not even depending on a font file?
