Added basic searching for moh (#1614)

added basic searching for the default moh directory
added app_defaults so moh is configured/repairable with app_defaults
changed to use PROJECT_ROOT
changed template replacement to be encased in comment so xml will
validate
changed to use preg_replace so leading spaces and tabs can be stripped
(to output clean xml)
local_stream_conf dos2unixed
made default search consistent (they should all be music/default or
music not a mixture)
