UserActivityStream -- used to create a full activity stream including subscriptions, favorites, notices, etc -- normally buffers everything into memory at once. This is infeasible for accounts with long histories of serious usage; it can take tens of seconds just to pull all records from the database, and working with them all in memory is very likely to hit resource limits.
This commit adds an alternate mode for this class which avoids pulling notices until during the actual output. Instead of pre-sorting and buffering all the notices, empty spaces between the other activities are filled in with notices as we're making output. This means more smaller queries spread out during operations, and less stuff kept in memory.
Callers (backupaccount action, and backupuser.php) which can stream their output pass an $outputMode param of UserActivityStream::OUTPUT_RAW, and during getString() it'll send straight to output as well as slurping the notices in this extra funky fashion.
Other callers will let it default to the OUTPUT_STRING mode, which keeps the previous behavior.
There should be a better way to do this, swapping out the stringer output for raw output more consitently.

Notes:
* Mapstraction causes JavaScript errors in XHTML mode, breaking our code if we're run later so the link doesn't work to get back to Desktop.
* not 100% sure how safe feature detection is here?
* Currently will be useless but visible links if no JS available; need to fall back to server-side for limited browsers
Regressions caused by bad refactoring in commit 21feac3bea.
Test cases in tests/CommandInterpreterTest.php were made against the pre-refactoring code, and now check out with the fixed code.
Failures were caused by not changing logic structure when moving from multiple exit points (each if point would return directly with a null or an object) to setting a result variable and then falling through to a common exit point. Without the if statements being restructured, the result variable would just get overridden by the next case.
I've extended the rights framework (centering on the Right class and Profile::hasRight()) to cover
Web login and API use. This will make it possible to prevent login and API use by users.
I added two new Right constants to the Right class: WEBLOGIN and API. I check these rights using
Profile::hasRight() when initializing users. If the rights check fails, I throw an exception.
I created a new AuthorizationException class for this particular
exception, in order to allow a different UI for these kinds of exceptions (or whatever).
