Changed font generation to take a filename instead of a directory to remove filenames from the control files.
Switched configuration files from INI to YAML.

- Using pyaml instead of ConfigParser
- Passing configuration objects instead of having file parsing inside the font classes
- Added commented-out stubs for the comparison merging
- Makefile: Updated to pass in the new yaml paraneters instead of INI filenames
- generate.py: Removed row/column variables to use the counts implictly from configuration file
Uncommented the code to actually use the generated font in the comparison images.
