lexer now produces a vector of heap allocated tokens

Browse Source 
This removes the problem of possibly expensive copies occurring due to
working with tokens produced from the lexer (that C++ just... does):
now we hold pointers where the copy operator is a lot easier to use.

I want expensive stuff to be done by me and for a reason: I want to
be holding the shotgun.
