Bug 6399 - tooltip for tags that says 'separate by comma'

Bug 6399 - tooltip for tags that says 'separate by comma'

Some sites split tags on spaces, some on commas. Since Koha splits on a
comma, we should make that clear to the patron. This patch adds
additional text to the "New tag(s)" label.

To test, enable TagsEnabled, TagsInputOnDetail, and TagsInputOnList.
Click "Add tag" on both OPAC search results and an OPAC detail page.
Confirm that the revised label appears correctly.

All tests pass. There are some more places where we can
add tags to multiple records at once, I noted them on the bug.
