Fix for bug 6991, replace registrars timer tick

Browse Source 
Registrar schedules an event every second to do
fRoster-CheckSanity(). This uses 2.5% cpu on my machine
when idle. Changing it to five seconds lowers it to 0.1%

waddlesplash then pointed me to this bug which changes it
to watch for team deletion and call fRoster->CheckSanity()

As I know little in this area, it's mostly based on what
LaunchDaemon does in MessageRecieved.
