The new DeleteaccountAction lets a user delete their own account
(subject to global rights set by the admin). It presents a form to
delete the account, with an "I am sure." text entry box.
It then schedules the account for deletion and logs the user out.
Feed for group memberships, in activity streams format.
Shows a feed; has proper pagination; accepts activitystreams "join"
activities to start a new membership.
common_shorten_links() can only access the web session's logged-in user, so never properly took user options into effect for posting via XMPP, API, mail, etc.
Adds an optional $user parameter on common_shorten_links(), and a $user->shortenLinks() as a clearer interface for that.
Tweaked some lower-level functions so $user gets passed down -- making the $notice_id param previously there for saving URLs at notice save time generalized a little.
Note also ticket #2919: there's a lot of duplicate code calling the shortening, checking the length, and reporting near-identical error messages. These should be consolidated to aid in code and translation maintenance.
Now, when you first come up the checkbox will most likely be off and the button to create an address is grayed out.
Checking the box enables use of the 'new' button to generate an email address -- it's left disabled until you check the box, so you can't accidentally trip it.
Actually adding the address now enables the post-by-mail option, as well, thus ensuring that it's saved. WARNING: OTHER CHANGES ON THE FORM WILL STILL BE LOST.
Removing the address now disables the post-by-mail option, so it's not sitting around confusingly enabled but useless.
You can still disable the checkbox manually without removing the address, in case you want to keep it for later.
It's also still possible to actually save it in the state where the option is enabled, but there's no configured address, but that shouldn't happen too often. Possibly that should be prevented outright though.
max_id is not yet implemented, as it'll need support added to the search backends. (since_id we get 'for free' by just cropping off the list, it'll do for now)
