=== TODO ===
- Implement single mode Batch Manager
    Probably use prefilters combined with "loc_begin_element_set_unit" (found in event tracer)
	SOURCES: "loc_begin_admin": http://piwigo.org/forum/viewtopic.php?id=17468
			 "use prefilters": http://piwigo.org/forum/viewtopic.php?id=17551&p=2
	- This is almost done, except that you need to refresh the batch_unit page, to see the updated copyright
- Add Icon field to copyrights
- Show the copyright when image is displayed
    (It doesnt show a picture yet, but it does show the name of the copyright)

=== Bugs ===
	- If you create a new copyright with a name that's already used
	- Description doesnt show with the copyright info (on the admin page)
	- The warning triangle saying our plugin does not seem compatible (version: ...)
	- Cannot create a new copyright??? (i assume its fixed, but Johan did, so he can remove the todo ;-) )
