UP-4156 Upgrade to released fluid 1.5.0

I performed basic testing; universality, Respondr, and mobile seem to be fine.  Drag and drop works (UP-4000 not fixed) for portlets and tabs.  General layout and navigation works. Manage Groups/Users works, email preview works. Tested the items I recall fluid 1.4.0 to 1.5.0 gave us trouble with.

It would be great to get some additional testing, but my initial testing is this can be included in uPortal 4.1.0 GA.

FYI fluid 1.5.0 released about 7 days ago.
