uncommit: add options to update to the current user or current date
These are also from the evolve extension's version of uncommit.
I tried adding validation that both forms of user or date can't be specified at
the same time, but that fails because these show up in `opts` with a None value
whether or not the option was given on the command line. Presumably that means
the conditional in `resolvecommitoptions` could be simplified. But this is how
both evolve and MQ handle it.
