[2.0] Fix some grammar errors

I've noticed that with network services, like NickServ/ChanServ/etc, there are some grammatical errors with the whois output from them, example: `ChanServ is an ChatSpike Service`

There's also repeated output if you have `m_servprotect` loaded, example:
````
ChanServ is an IRC operator
ChanServ is an ChatSpike Service
````

So, this update fixes that by checking to make sure the oper-name is not `Services` when outputting the `is an IRC operator` line, and then changes the services-line given by `m_servprotect` to the following: 

`ChanServ is a Network Service on ChatSpike`


This hasn't been tested as I don't have a test-net with services enabled, if anybody could test it that would be great. It DOES compile.
