prosody.cfg.lua.dist: Remove comment about mod_*.lua above modules_enabled This is a very old statement, but people generally don't need to check for the files, and shouldn't be encouraged to put them in Prosody's source dir. The installer will be the way forward for most people, and hg for the rest. Manually moving files into the right place is not something most users should be doing.
