Add more internal fonts

[ColOfAbRiX]

Description

Figlet4s is a "battery included" library and it already ships with many internal fonts but many more are freely available online. Top up the internal fonts shipped with Figlet4s.

There are a number of places where more fonts can be found:

• http://www.figlet.org/fontdb.cgi
• https://github.com/xero/figlet-fonts
• http://www.jave.de/figlet/fonts.html
• https://github.com/cmatsuoka/figlet-fonts

Figlet4s includes rendering tests for all the fonts in the library. All the new fonts must pass the test. Some of them might not for several reasons: they might be corrupt, designed badly, they might use undocumented features. Depending on the nature of the problem a case can be made to include the font in the library but skip the testing.

P.S. Pay attention to the encoding of the original font so that they are rendered the same way

I started adding Commodore64 files from https://github.com/cmatsuoka/figlet-fonts. I decided to add support for directories for the internal fonts, to keep things organized.
