Add quoting sensitivity to word_wrap() re-wraps quoted text to still fit.

Currently, the options are [width [, orig_width [, [quotes]]]
That should be updated to allow the boolean to be pretty much anywhere
fitting with the rest of the JS stuff... but I'm too lazy.

Also, this should (probobly) be moved somewhere else so that the internal
editor could make use of it too.

Further, should this optionally support ANSI, pipe-codes, and WWIV colour
codes?
