Wrote a basic README.
Slightly changed README.
Set up the build system and implemented config management and logging.

The build system uses CMake to automatically generate dependencies. It
also automatically finds all files since all of the necessary files are
already created. This circumvents a nasty limitation of CMake that would
occur if new files needed to be added later in the program.
Minor config manager style changes and started the display manager.

Implemented video modes in the display manager.
Minor style change and added pixel manipulation in the display manager.

Filling a rectangle is implemented but not filling a circle (or maybe a
rounded rectangle too).
Added an install target and implemented fonts in the display manager.
Merge branch 'master' of github.com:philarin/Pong
