Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Boolean options can be adjusted from the gui now (using a very basic widget). Also some bug-fixes. Fixed a minor bug where layouts with the same id but without shared alignments would be messed up. Tracked down the "nothing trawn until a resize" bug (see jobs.txt). If widgets throw during creation they're now replaced by debug widgets. Function pointers are converted to delegates using a safer method.
