[bin] fixes: org-mode-gcal

This worked well in the terminal but would fail on cron, as it used a
different home directory. Also, there would sometimes be problems
starting the server. Changes:

- Fixed hashbang

- Now takes one argument; the directory to run it in. If no argument
  supplied, will run in the current directory. This is how emacs files
  init files

- Now assumes TCP & server-files rather than unix domain sockets. This
  should make running multiple named servers more reliable
