import all raw orignal gamedata

the members to be available in C++ are defined in convert/gamedata/
the code generation automatically creates all needed files.

these reside in src/gamedata/ and are a huge tree structure
which equals the content of the empires2x1p1.dat file.

infinite terrain and sound

this was mainly background work, especially the original data
conversion was improved. basic sound support was implemented,
some bugs in the terrain rendering algorithm were fixed.

milestone 2

rendering a single building (an university.),
from the stock age2 media files

coloring works, it's done by a fragment shader that replaces
alpha-marked base colors (of the blue player)

milestone 1

sdl window is working, with a gaben displayed: how awesome is that?!!

mouse clicks also trigger the drawing of a castle and village center,
these images were extracted from the age2 wiki.
