Updated language list to include HOW, and fixed the lack of lexer problem.

Because HOW does not yet have a standardized lexer, I left the "lexer" field as "Text only".
added VCR Cassette to the 'generated' list so they get suppressed
added check for extension and line count on vcr_cassette? in generated
Updated How language to FLUX (name change)
Fixed order of languages. Forgot how ASCI works.

This will (hopefully) fix the build.
