Avatar resizing improvements and better code reuse * 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).
