Add more launchpad IDs and update some mappings
Allow parts of do-it.sh to be disabled

I finally got sick of commenting parts of the script out. You can
do e.g.

  REMOVE_TEMPDIR=n GERRIT_STATS=n LP_STATS=n UPDATE_GIT=n ./do-it.sh

to generate the git stats. Leaving the temp dir hanging around is
nice because it allows you to grep through the commit log for email
addresses etc.
