Override is a valid tag

[cocoabythefire]

I just ran into a validation issue where override was flagged as invalid. I think this is all that's needed to fix that.

Seems valid. http://usejsdoc.org/tags-override.html

"override" should be above "overview" in the list ) Maybe it would be easier to merge #178 that fixes the same issue.
