follow includes for commandline/library compiles problems

[weyrick]

for stand alone apps, we follow includes. for libraries we don't. this in itself needs to be made more clear.

further, we fail with a nasty bigloo error if a user compiles a stand alone application and lists one of the auto included fails on the commandline as well. e.g.

ERR: File "test.scm", line 117, character 3867:
ERR: #  (define +include+:lib/a/test2.php

should we allow multiple files to be listed for command line apps at all, then?
