Bug 182521

Problem -
During my day to day photo management I have on many occasions added several tags to multiple pictures. After reviewing each picture more critically, I then later decide that none of the tags apply to the specific picture. In this case I'm required to remove each individual tag instead of removing all tags in a single operation.

Steps to Reproduce
- Add multiple tags to a single file. Notice how this operation allows the user to apply multiple tags in a single operation if they decide to highlight multiple tags in the left hand column of the main UI.
- Now attempt to remove all tags or multiple tags from the image in a single operation. 
NOTE: While deleting the image does accomplish the task of removing all tags in a single operation, it is not the desired single operation I'm looking for :)

Expected Behavior -
The Edit | Remove Tag and the right click on image Remove Tag UIs should include a "Remove All Tag" option at the bottom of their list of options. This may look similar to the Edit | Attach Tag menu where the "Create New Tag" is an option at the bottom.

Also, viewing how the hierarchy of the Attach Tag works, I realized that it takes into consideration the parent and child tag relationship in the way it presents the information to the end user. I think this hierarchy should also be incorporated into the Remove Tag UI. This way the user could choose to remove the parent tag and then all children tags are automatically removed as well in a single operation.

Another way of having the user remove multiple tags in a single operation might be to allow them to Ctrl + select all tags they would like to remove. Once all tags are highlighted, the user would then initiate the remove tag(s) operation.
