Generate font installation instructions and include with font bundles

[alerque]

In the event the project itself doesn't have it's own, we would generate an instruction file (INSTALL.txt or similar) with various platform instructions.

Each project could supply instructions (or opt out of including any), but how to install fonts on each platform is a pretty generic thing that font developers shouldn't have to worry about documenting.

My thought here would probably be a PDF instruction sheet, perhaps separate ones per platform. The source for these could be in Fontship, and a clean PDF with project specific file names could be generated for each dist package.

Specifics like how to choose OTF vs. TTF could be skipped for projects that only build OTF, etc.
