New form step for selecting a content model.
Updated for depreciated ingest functions.
Also Coding Standards.
Fixes property of non-object error.

islandora_object_load() can return FALSE, which is considered set (isset).
Changed the check to make sure it was an object returned, rather than just
check against null.
