Add an array of arguments to isReadOnly() method of actions, to let
them change their results depending on what actions are called.
Primarily used by the 'api' action. Ideally in the future that will be
multiple actions. But this might still be useful.
We show stats, subscriptions info on the personal page in the sidebar.
Pushed code from showstream.php into a common parent class for
personal and profile.
I got a little sick of trying to keep the export data and <head> links
synched in actions, so I made a common method, getFeeds(), which gets
the feeds for both. It returns an array of Feed objects, which know
about what their mime type is, title, location, all that jazz.
I changed the FeedList class so it handles the new Feed objects
instead of the old array of data.
I changed all the actions that show feeds (I think...) so that they
now use getFeeds() for all their feed needs.
My attempts here are to mimic the `pagination()` method shared by
actions. I'm tentatively adding the `$count` property to actions so that
we can query the number of notices ''being displayed'' per page prior to
calling the actual `pagination()` method itself, since document
relationship `<link>` elements need to be output inside of `showHead()`,
before `showContent()`, which is where `pagination()` is, gets called.
These extra `<link>` elements only appear on pages where pagination
makes sense. They trigger functionality in some user agents, such as
Opera's Navigation Bar for more easily navigating forward and backwards
across a paged set of notices, messages, or group lists, etc.
Moved the common_avatar_* functions to the Avatar class. Typically
either as methods on the object or as static methods. Replaced all the
uses of the functions in other modules.
