how to include OTP defiened applications in resourse file

[Vance Shipley]

Thinking about this I wonder why we put stdlib in the applications
key (of the application resource file) instead of the 
included_applications key.  Since stdlib is a code library, and 
doesn't include a mod key in it's application resource file, it
would seem that it belongs in the included_applications key.

I assume it's for historical reasons.
