At the moment EditTags uses the new bulk APIs that support select all. However the other actions (download) work in the old way and would have to be refactored to use the new APIs.

In this story we'll implement the following behaviour:

• Download: When "select all" is enabled, the whole contents of the current folder should be downloaded as a ZIP.
• Edit Tags/Categories: Enabling "select all" should not disable these options; additionally, an info message should be displayed in the modal warning users about folder not being processed.
