func_groupcount.c: Adding Group Variables + additional Group functions
DumpGroups
-------------------
* New application. This will dump all channel group membership and associated
variables
Groups and Group Variables
------------------
* Group variables can be set on a group once the group is created
When a group is destroyed, all variables on that group are also destroyed
A group variable is somewhat like a global variable, but it's on a per-group
basis.
GroupSet - Adds functionality to the manager to be able to set a GROUP()
on a channel.
GroupsShowChannels - Show each channel and it's associated groups
(a channel will be repeated for each group@category
it's a member of)
GroupsShowVariables - Show variables in each group@category, one event per
group, all variables are contained in each
group@category event
GroupVarSet - Set a group variable (the group must already exist)
GroupVarGet - Get a group variable
* New Manager events:
------------------
GroupCreate - Event is fired any time a group is made,
ie: Set(GROUP=x) or Set(GROUP()=x@y).
This event is only sent on when a channel is added to a group
