c80d6974cb Substitute defines with their strings. 
Before allocating space for a token, the lexer will first check to see
if that token is a defined name. If it is, it will allocate space for
the defined string instead.

A test file is included in programs/tinyvm/preprocessor to demonstrate
the behavior. When functioning, the program will print the fibonacci
sequence.
