noticesWithFriends is turning out to be one of our most expensive
queries. The join is costly, and this method is hit over and over and
over by desktop clients and other API users.
So, I've added a first pass at caching the results. I store a "window"
of notices -- equal to the first 3 pages of notices, plus one for
pagination -- in the memcached cache. If with-friends notices are
requests, I fetch the whole window out of the cache and grab the slice
requested. If the requested notices are outside the window, we just do
the query. If there's nothing in the cache, we request the window and
store it, then return a slice.
I had to add a NoticeWrapper class that works like DB_DataObject
(well, just the fetch() part...) but just holds an array of notices
instead of a DB cursor.
Finally, saving a new notice blows away the caches for subscribed users.

* No need to check $source's value before inserting
* No need to update the notice if the $uri was known in advance

Ran everything through php -l, found out that it didn't compile.
So: fixed the am-I-running-in-Laconica check at the top of each file.
Some syntax fixes in shownotice, showstream, common.

Did considerable work on the settings section.
Redesigned the DB to allow avatars. Each avatar image has a size and
an URL. There can be multiple avatars per profile, just different sizes.
Added accessors in Profile for avatar. Show the avatar in lots of
places, where it makes sense. Constants for avatar sizes in common.php.

Added GNU Affero GPL license block to source code.
Added name "LACONICA". I think it should work fine.
