Tags with trailing spaces

[Nateowami]

Tags with trailing spaces are causing an issue. See "Jesus' Deity ", and "Creation ". They are both listed on the tag cloud, but the page the link brings up doesn't show any verses. This issue also surfaces when you attempt to add a verse in learn mode. Searching for "Creation " or "Jesus' Deity" doesn't bring anything up, although the "Creation " tag mysteriously works on the add verse page. I believe the solution would be to strip trailing spaces when tagging verses, and then clean the tags that have already been added.

Note: The URL for the tag doesn't include a space (%20), but the text on the page indicates that the tag has a space, which is sort of odd, since I'd think it wouldn't be able to find the tag at all.
Note2: As with most tables, if no verses were found, it should specifically say so.
