Add ignore system support
Merge branch 'master' of github.com:gajop/uberserver-1
add sourceUser explaination
mods cannot be ignored; sourceUser -> sourceClient; using self.clientFromUsername(username, True)
removed ig compatibility flag
now using user id instead of user name for db methods
minor fixes
remove all cases of admin/mod ignores when a user becomes a mod via SETACCESS; allow SETACCESS to affect offline users
now preloading the ignorelist (most checks are done in memory)
add a limit to the amount of ignored users (hardcoded)
added named params to IGNORE/UNIGNORE commands
avoid storing ignore reason in memory
