Steve Fryatt 0ab5fe7c02 Improve URL handling in URL Bar. 
Rationalise handling of UTF8, so that URLs are always converted into local encoding even if there is no URL icon present.
In addition, make preliminary hotlist test in set_url() use local encoding, in line with all subsequent checks.
Make handling of over-length URLs more sensible: warn user and completely blank the URL bar.
