Split indexing Rake tasks to: `monsterfork:index_statuses` (reindex statuses that do not normalized text yet), `monsterfork:reindex_statuses` (reindex all statuses), and `monsterfork:reindex_media_desc` (reindex statuses with media descriptions). These tasks are only needed by admins setting up Monsterfork for the first time or if the normalization scheme has changed drastically.
