Initial commit
Added partway relx support.

Right now, relxrun requires "application:start(lager), application:start(uffda)."
at the shell before it is running, and it isn't clear why. Otherwise, the configuration
is most of the way there.
Handled 'DOWN' infos from crashing services.
Added a basic testing harness, but the Makefile has complicated targets.
Removed lager and erlang_commons dependencies.
Uncommented monitor functionality.
Merge pull request #1 from th0114nd/master

Removed dependencies, created test harness.
