Subject: Add a 'run' command to run the relx release

Should only be used during development. Stolen idea from
Tristan Sloughter who stole it from Ahmad Sherif.

This commit also introduces the 'erlang' function for
executing Erlang code written directly in the Makefile.
The rest of the project will eventually move to using it
as it's much cleaner than the previous solution.
