Application bulk operations

tagging for sprint.

Clarifying this a little:

We need to implement hook_action_info() and create actions for changing an application entity's status (ie changing it's "status" property from 0 to 1 and vice-versa).

Once this is done, VBO will automatically pick them up.

This has already been done in application entities for the delete action and is just a matter of pretty much duplicating the logic for changing a property value. Note: we'll need one action per status (active and inactive).

Oh wait, I already did this and forgot there was an issue for it :)
