[erlang-questions] Ability to add app directories explicitly for reltool

I'm sorry, my explanation was really messy.

It seems like in that case reltool will *see* and somehow *validate*
all Erlang applications it finds in the "lib" directory, no matter if
they are included into reltool.config or not. Maybe this should be
considered as wrong behavior.

So, in my example erlson wasn't included anywhere in reltool.config.
It just had 'erl_parse' module included into the application. Btw,
apparently Anton has recently removed erl_parse.erl from his
repository, just because it had been causing problems with release
package generation.
Of course, this error is quite specific, but maybe there are more
possible errors that I just don't know.
