I added dry-run to p4SyncMissing some time ago; I don't remember if I finished it, but I don't have time to test, and don't want to lose it, so submitting it. Wow is this a rough testing branch or what.

Add TODOs.
Fix some directory bugs when running scripts with a cwd not in the p4 workspace. TODO: make sure all scripts and options work when run outside p4 workspace.
If user isn't logged in you can get weird errors later on in the pipeline, and without extra manually added prints, you wouldn't know you just need to log in. Added TODO: about detecting if we need to do a p4 login.
Some of my stuff seems to have stopped working with later version of Python/p4, had to update string to byte string; no doubt more of these issues hiding.
Haven't tested on python 2 in a while, do not consider these working there.
