wrong loop control in luaA_parserc

[M. Dietrich]

hi,

when no config file is found strange letters are printed on stderr.
cause for that is the loop in luaA_parserc which should be
top-controlled.

also awesome just stays but does not allow any interaction - i would
prefere a logg-message and terminate awesome in that case.

see the patch attched, best regards,
        michael

Subject: [PATCH] fix loop over config files if none was found

	if no file was found the string is just "\0" and neads a head
	controled while

	if no config file was found exit awesome with an error message
	(fail early!)

	add success logging when a file was found
