scripts: Renamed import math alias m -> mt

Browse Source 
Mainly to avoid conflicts with match results m, this frees up the single
letter variables m for other purposes.

Choosing a two letter alias was surprisingly difficult, but mt is nice
in that it somewhat matches it (for itertools) and ft (for functools).
