RaidRange

New functionality "/rr inverse": toggles tracking raid members outside the range check instead of inside (no idea if this is useful for anyone).

Multiple very minor performance increases:

• Previously always scanned raid1-raid40, now only scans the actual number of group members
• No longer checks the type of group (raid/party) every scan
• Everything that can be a local function/table now is
• No longer redraws parts of the range UI that did not change
