rewrite revert command. fix issues 93, 123, 147. new version does these things: - saves backup copies of modified files (issue 147) - prints output like other commands, and errors when files not found (issue 123) - marks files added/removed (issue 93)

ssh: skip noise generated by remote shell we send a dummy command with known output to get in sync

work around python bug on solaris 10. write to file opened mode 'a+' should write to end of file and update offset pointer, but does not (solaris 10 has python 2.3.3). fix is to always seek.

more windows fixes.

clean up lee's windows testpid fix.

Use [ x = y ] instead of [ x == y ] in shell scripts.

New option -i/--ignored for 'hg status' to show ignored files. localrepo.changes() now returns an additional list of ignored files if it is called with show_ignored=True.

Fix hg push and hg push -r sometimes creating new heads without --force. Fixing issue179. The algorithm checks if there not more new heads on the remote side than heads which become non-heads due to getting children. Pushing this repo: m /\ 3 3a| |/ / 2 2a |/ 1 to a repo only having 1, 2 and 3 didn't abort requiring --force before. Added test cases for this and some doc strings for used methods.
