[cp-patches] FYI: WrappedPlainView additions make line-wrapping work!

[Anthony Balkissoon]

I added a lot to WrappedPlainView (and fixed a bug in Utilities that I
mentioned in a previous email) to make line-wrapping in JTextAreas
actually work!

Of course, when testing, I hardcoded into JTextArea that it's View
should be of type WrappedPlainView so I could see the line wrapping
working.  This is incorrect and I didn't commit that.  WrappedPlainView
should be set as a JTextArea's View when setLineWrap(true) is called.
Once this is working (soon), you'll be able to see the line-wrapping
working.

I also haven't done a whole lot of testing, just a one-time insertion of
text and it wrapped properly, so I'll have to test (and fix) this much
more.
