Merge lp:~kfogel/launchpad/538219-debdiff-is-patch-too into lp:launchpad

[Karl Fogel]

When a plaintext file with a name ending in ".diff", ".debdiff", or ".patch" is offered by the user as a patch attachment, have Launchpad trust the user and not prompt for confirmation.

[Abel Deuring (adeuring)]
