Store tags in one big pre-allocated string and only work with refs

Browse source 
This should decrease the number of allocations before main is entered
significantly, but complicates the code somewhat in return.

Assuming I used `massif` right, doing just `SelfTest --list-tests`
went from 929 allocations at "Remove gcc-4.9 from the travis builds"
(2 commits up), to 614 allocations with this commit.
