Added an overload of SkTQSort that sorts an array of values, rather than an array of pointers.

Added an overload of SkTQSort that sorts an array of values, rather than an array of pointers.

Also added some parentheses to all the QSort variants to get rid of a gcc warning.

I needed to sort a simple array of integers and the 2 existing QSort variations
either sort an array of pointers, or use a comparison function and context
reference that I don't need.

Since this new overload could also legally take an array of pointers, and I'm
not sure how smart compilers are about template param inference (VS and gcc
don't seem to have any problems with it), it might make sense to name this
differently to prevent ambiguity (if so, any suggestions as to what to call
it?).
