Added exception catching with printing to thread-safe console. Removed press enter call.

Changed output a little bit.

Also just realized it actually should be easy to parse `p4 fstat ...`, I
just need to crab the clientFile output, and this script should be sped
up substantially. I need to figure out the best way to break this down,
don't want it to be called on a huge directory, but each subdirectory to
split up the work.  That said, that would miss the top level files.  A
good alternative to not waiting is to see if I can grab the process
output while it's working, instead of waiting for it to be done.  This
would actually work perfectly; it's just tricky trying to figure out if
I can break this up. This would also still delay the start of the
script.  Could do a mix of local and tree based fstat.  Start with local
and switch to the tree.
