As phase 1 of allowing meaningful frontend progress metering, a frontend has
to be able to run duplicity in 'dry run' mode, where it calculates what needs
to be done, but doesn't do anything.

This means no writing to the backend (and ideally, no tarring, as that just
wastes time/space).

Here's a patch that adds the command line option, and for several of the
commands that make sense (backup, restore, remove_old), supports 'not doing
it' when dry run was specified.

It also added some missing statistics hooks to the non-sig-writing version of
DiffDelta.  I think their absence was just an oversight before.
