Improve href() with a faster trim end splat

[ngbrown]

This is a small optimization to href() to not use a backtracking regex on splat paths.

The speedup of the new trimEndSplat() method over the regex /\/*\*?$/ is about 17x to 36x speedup: jsbenchmark.com benchmark

The speedup of all of href() with options is about 1.2x to 1.5x speedup: jsbenchmark.com benchmark

This could also apply to compilePath(), but that only runs once per path at application load, not many times per page in the React render loop.
