Code review comment for lp:~ken-brotherton/boots/localization

This branch is not ready!

It currently uses the localization domain "fslint", apparently ripped straight from an example. In addition, it munges already corrected headers, and steps on the definition of is_interactive in boots/lib/ui/generic.py -- reintroducing a bug.

Please make sure to review the complete diffs every time you merge -- and critically look at the code! This was a bit sloppy.
