Fixed a crash when running beshare with our BTextView (thanks to Andrew Bachmann for reporting), though it's a bit hackish, added some printfs to TextView.cpp to help finding/fixing bugs, a small optimization to WidthBuffer. Should convert and commit WidthBuffer's tests to cppunit tests sooner or later.
