Fonts with failing tests

[stefanor]

Currently skipped in the test suite (as of #115):

• crawford2
• konto_slant
• danc4
• diet_cola
• stronger_than_all

They need more investigation. Either bugs in the fonts or pyfiglet.

Crawford2 should be addressed by #118.

[peterbrittain]

Stronger_than_all handled by whitespace fix.

Konto fonts look like they're hitting some bad unicode, so probably need some editing.

Pyramids looks like figlet is bugged, so I don't propose fixing.

That leaves danc4 and diet_cola.

[peterbrittain]

Turns out I had a little time to look at this...

• danc4 was caused by premature optimization of an empty definition for " ", which broke the line splitting logic.
• pyramid was a bug in figlet - it can't handle character 129. Converting the font to use 128 instead fixed it.
• diet_cola was not defining rectangles for every character and so broke figlet and pyfiglet differently.
• I also fixed the 5x8 font, which was using the wrong height in the header.

Propose we live with konto decoding issues and close this now.

This seems reasonable to me. Thanks everyone for your hard work keeping on top of the things you noticed by filing and fixing issues. Closing this one for now, please file new issues for specific cases.
