TODO for VCP

*NOTE* Doing a `grep -r TODO lib bin` will find lots of small things and
future feature ideas.  This file will grow to include the more important
of those.

- Bugfixes
  - Make <rev_root> and <name> escape their characters
  - VCP::Dest::cvs needs to set the binary mode properly on files it
    creates and checks in
  - VCP::Source::cvs needs to deduce binary modes correctly

- Feature Adds
  - Need to make the transfers more transactional, so we can recover
    from where we left off when something fails.
  - Need to save some sort of state as to where the last export ended
    so the next one can start from there.

- Efficiency
  - The cvs drivers can be made faster
