Make wordwrapping functions take font arguments

Browse source 
They need to know how wide the text is going to be in a particular
font, so font::string_wordwrap and font::string_wordwrap_balanced now
take a flags argument like all the printing and dimensions-getting
functions. next_wrap and next_wrap_s take a Font* now, they're internal
to Font.cpp so they can take a Font and avoid double flag-parsing. But
if any non-Font.cpp code needs next_wrap/next_wrap_s in the future, I'd
just make a public wrapper that takes a uint32_t flags and passes the
Font* to the internal functions.
