*Really* fixed problem with non-positive retains this time

Moved compound edit setup inside try/catch

Do not add remote operations to local undo stack

Fixed bugs in operation serialization/deserialization

Some more specific logging in server

That explains why I wasn't logging client callbacks...

Still need to continue poll cycle in the case of empty ops

Fixed operation reparenting issue coming from AwaitingConfirm at non-init

Do not send non-positive retain values (fixes issue #14)

Merge remote-tracking branch 'candera/update-cccp-emacs-url'

Merge remote-tracking branch 'candera/make-agent-more-robust'

Hard-code /tmp on platforms other than Windows (otherwise logs are impossible to find on Mac)

Update README with new location of cccp-emacs

Allow agent to be run from any directory.

Add execute permission to server.
