Resolution fix.

Starts fullscreen in desktop-resolution.
Arguments 1 and 2 can be width and height, if present, it starts in
windowed mode. If argument 3 is present, it starts in fullscreen in the
resolution descrbed by 1 and 2.

Example:
./binary # starts in desktop resolution, fullscreen
./binary 800 600 # starts in 800x600 in a window.
./binary 800 800 f # Starts in 800x600 fullscreen.
Added defines for console-colors.

TXTCOL_* Can be used to color strings, easier to remember than ^NUMBER.
Pimped the console.

Added lines and a background box for the input line.
Added wireframe render, clayrender, fullbright.
Removed unused line.
Input "working". :)
