Merge lp:~gmb/launchpad/non-js-muting-bug-734732 into lp:launchpad

[Graham Binns]

[r=bac][bug=734732] There is now a non-JS process for muting mail from a bug.

This branch adds a BugTask:+mute view, so that stick-in-the muds who use
console-based browsers (RMS, I'm looking at you here) and people who use
browsers that don't play nice with YUI 3 (IE, now I'm looking at you)
can still use the mute / unmute functionality.

The +mute view presents a single button that allows the user to mute or
unmute bug mail for a bug. If the +mute page is visited by a user who
already holds a mute on the bug, they'll be redirected to the +subscribe
page, which handles the unmuting (and resubscribing if desired) story.

[Brad Crittenden (bac)]

Looks good, Graham, nice and simple.

I have a few issues:

1) You are inconsistent in text presented to the user of "mail" vs. "email" but definitely not "e-mail".

2) The phrase "Bug mail for bug X" is wordy. s/Bug mail/Mail or Email.

3) In test_bug_mute_self_view_mutes_bug it would be nice to see the user is not muted before you exercise the form.

review: Approve (code)

[Graham Binns (gmb)]

Thanks Brad, I've updated the code as you've suggested.
