mnussbaum c6d757f198 Decrease startup-time by avoiding iteration over maps ...

This commit makes adding, removing and finding key maps an O(1)
operation instead of O(n), where n is the number of pre-existing maps.

In my testing, averaged over 100 iterations, this reduces the time spent
initializing NERDTree at Vim startup from ~73ms to ~9.7ms. That's with
only the default included key maps.
