PM on Group Change 2.0.2

This mod adds the ability to send an automatic PM to your members when an admin edits their primary group from the ACP.

[b]Features:[/b][list]
[*]No file edits, coded as an hook!
[*]Easily enable/disable the hook from the Admin CP
[*]Ability to specify always the same account to send the PMs or use the account of the admin that edited the group
[*]Ability to exclude certain groups by default from receiving a PM (useful for the banned group)
[*]Ability to setup a custom PM subject and message from the ACP with some quick tags (member name and new group name)
[*]New options in the ACP near the dropdown of the primary group when editing a member to not send a PM to individual accounts
[*]The hook itself makes use of the MemberSync option so every time the group changes a PM is sent
