uncommit: add a new flag `--revert` to discard wdir changes after uncommit

This patch adds a new flag to `hg uncommit` using which one can discard the wdir
changes which are left after the operation. Both the changes, the ones which
were before the uncommit and the ones which were added to wdir as a result of
uncommit as cleared out.
