Fixes for bridge setup, and root/shell interaction 

- If you paste bridge addresses from Gmail, you get some strange
characters that were causing problems. This looks for that, and
other formatting related gotchas.
- This also moves all configuratino to the torrc.custom file
instead of using the control port. These changes require you to
restart anyhow, and using the torrc.custom is more reliable as it
affects the tor process on launch, and not post control port interaction.
