#1952 Add bulk tagging to the Organize module.

Allow a user to highlight one or more items (images, videos, or albums), and enter a tag (or tags, comma delimited) and apply it to all of the selected items. The code is based on the batchtag module.

If the tags module is not enabled, no changes to the Organize UI will be shown.

Fix comment typo.
After finding a test in Item_Model_Test that didn't end in the string "_test" and
fixing it in 9ba9f3953132c5c5de9efb0a4724c7b9300dc9ea I decided to write a test to make
sure that we don't have any other overlooked tests.  We don't.
