Replace theme HTML with *almost* the latest stuff from the
mockups. (it doesn't include r18467 yet).
Our theme format is now modelled after WordPress / Habari's style
where you have one entry point per type (eg: album.php) which can
load up whatever parts it needs (eg: $theme->display("header"))
Created album and photo helpers which have create() functions
that form the base of our new API, along with tests for them.
Created our own version of the ORM_MPTT since the existing
versions were too buggy and unsupported to depend upon. Only has
a minimal implementation so far, and the tests are not yet
committed.
Added path(), thumbnail_path() and resize_path() to Item_Model
Extended the scaffolding to allow you to add lots of
photos/albums into your hierarchy.
Deleted modules/mptt -- we're not going to use this anymore.
