cyrusauth: Fix user creation
Fix support for /msg @#chan :hi

005 STATUSMSG defines list of characters prependable to channel name,
but we used simple modes instead.

Fix #272

Thanks to grawity for the link to 005 docs draft, and to carrot for
testing the patch.
Return old fakeonline module as modules_online

It was accidentally dropped in 0.207 because of the confusing name,
it looked too much like antiidle module.

Instead, this module tells broken clients like Colloquy that *status and
*module are "online". Otherwise those clients require user to always
prepend messages to *module with "/msg *module", even if the window of
*module's query is active.

Also fix the module to support network modules
