Include text rendering code, a set of fonts and minimal configuration changes.

At runtime fonts are expected to be in a fonts folder relative to the config_dir or use the HERSHEY_FONTS_DIR environment variable.

In order to create a minimal set of changes I have not compiled these changes on this fork!

I'll add the fonts files separately as they are cryptic.

I'm going to close this and go a different route. What I didn't know until I got this PR was that Hershey fonts don't do Mandarin or Hangul (which I wanted a new draw procedure to do) and that FFMPEG has the ability to implement this for installed true type fonts and easily manages various sizes, colors, FreeType flags, etc.

I've been able to prototype the FFMPEG implementation today so I'll be trying to fully implement it over the next week or so.

Please note that I do appreciate your work to create the PR. I just think that using the FFMPEG option with the FreeType backend will provide a better overall experience for users.
