Title: Added support for base32 and base64 numbers and double-quoted strings and fixed rune highlighting.

I'm assuming that base32 and base64 numbers are grouped in fours, as with bin and hex (not three as with decimal). I'm also assuming that digraphs must not immediately follow alphanumeric characters.
