Separation of Network and Services in command hierarchies

[Xe]

A proposition has been made in #dev to separate commands that modify the network (such as AKILL/SQLINE, etc) from commands that modify services itself (DIE, MODLOAD, etc). I believe this is a reasonable proposal and should be implemented as such:

Two services will be created for management of the network and services itself. For now we will call the network side NetServ and the core side CoreServ. NetServ will contain the functions that manage network state such as banning people or nicknames. CoreServ will only contain functions to manage Arata itself.

Relates to #23

Thanks for writing up this issue. To clarify, I was the one who made the proposal so I basically have nothing else to say here. This issue doesn't really relate to #23 but does depend on it as the permissions system really needs to be implemented before this proposal can be worked on.
