* getOriginal added to Avatar class
This is a static function that retrieves the original avatar in a leaner
way than Profile->getOriginalAvatar() did (see below).
This will throw an Exception if there was none to be found.
* getProfileAvatars added to Avatar class
This gets all Avatars from a profile and returns them in an array.
* newSize added to Avatar class
This will scale an original avatar or throw an Exception (originally from
Avatar::getOriginal) if one wasn't found.
* deleteFromProfile added to Avatar class
Deletes all avatars for a Profile. This makes the code much smarter when
removing all avatars from a user.
Previously only specific, hardcoded (through constants) sizes would be
deleted. If you ever changed lib/framework.php then many oddsized avatars
would remain with the old method.
* Migrated Profile class to new Avatar::getOriginal support
Profile class now uses Avatar::getOriginal through its own
$this->getOriginalAvatar and thus remains backwards compatible.
* Updating stock GNU Social to use Avatar::getOriginal
All places where core StatusNet code used the
$profile->getOriginalAvatar, it will now useAvatar::getOriginal with
proper error handling.
* Updated Profile class to use Avatar::newSize
When doing setOriginal, the scaling will be done with the new method
introduced in this merge.
This also edits the _fillAvatar function to avoid adding NULL values to
the array (which causes errors when attempting to access array entries as
objects). See issue #3478 at http://status.net/open-source/issues/3478
lib/plugin.php now has a parent onAutoload function that finds most common
files that are used in plugins (actions, dataobjects, forms, libs etc.) if
they are put in the standardised directories ('actions', 'classes', 'forms',
'lib' and perhaps some others in the future).
