* now splits everything up into independent static libraries. * fixed a great deal of incorrect #include statements. all headers must now be specified with their full path relative to source. exception: if file being included and including file are in the same directory, no path needed. use <> when relying on the build system's include path (e.g. for system headers and external libraries, e.g. boost), otherwise "". * temporarily renamed maths/Vector2D to Vector2D_Maths to avoid conflict. these should be merged. * hacked around VC linker stupidness when building static libs; texture codecs must now be registered manually. This was SVN commit r3931.
