ANNOUNCE GWorkspace 0.4.6

[Enrico Sersale]

This is a bugfix of 0.4.5.

Only a bugfix, but, if you are using GWorkspace, get this version, because
a very old bug that caused gw to redraw the browser window too many times
during the file operations, has been fixed.
I've catched it for *years* and it was only a little stupid NSTextField
that, instead of calling -setNeedsDisplayInRect: (its rect) for its
superView, was using -setNeedsDisplay: causing the redraw of all the main
view :(((
