moderation production update

Finishes 99% of the moderation module.  Some fixed to reminders, twitch,
the example (Izl) module, the IRC libraries, and the startup procedure.
Core has a few new commands and command are handled in a much better
fashion, allowing commands to be blacklisted from being run outside of
core and commands now properly being reserved even when disabled.
Install script added for adding your database tables in properly.  Very
basic and has no checking for now.  May add a database toolkit later on
for updating.  Rainwave module makes its appearance with full
functionality completed and tested.  Works with all stations.  Reminders
updated to allow user activity as a requirement for reminders to be
processed.  If no user activity is detected within 10 minutes, reminders
stop being processed.  New base cURL library added for the radio
modules.  May be used by any module as a very light weight cURL
solution.
