Code review comment for lp://staging/~brian-murray/terminator/lp-links

This branch expands the linkification of LP: #1 to match the regular expression specified in the Ubuntu Policy Manual footnote 20. It is actually a bit more lax as people sometimes don't get the syntax exactly right and it would still be useful to have those typos linkified.

This also adds a new feature of linkifying multiple bugs in a list. For example:

LP: #180692, #415500

Both of these will become links to the correct Launchpad bug numbers.
