Eliminate @ignore and improve verbose of replies.

There is no need for @ignore (and it makes the command array unnecessarily long and I've improved the verbose of the turn on/off commands.  Also, I've added a couple of comments for improvement that are beyond my capabilities atm.
Create Coffee

Is exactly the same as Tea.cs only with Coffee...
Put @ignore back

Part one done, part two will be to use message handles for verbose responses as stwalkerster suggested.

Update my fork with current version
If !coffee is called with no parameters, helpmebot pours a cup for whomever asked for it.

Simon, I think this should be right (should work).  If it does, great pull it in and I'll update the others that should do this as well; otherwise, please fix any errors and add a little note as to why it wouldn't work like this so I can learn and I'll try again with another (probably "tea" next since this is based on that).  Thanks!
New ping command...

`!ping` pings Helpmebot ( replies with http://helpmebot.org.uk/wiki/Message:CmdPing )
`!ping <username>` pings <username> ( replies with http://helpmebot.org.uk/wiki/Message:CmdPingUser )
Rename ping.cs to Ping.cs
Add "Ping.cs" to includes
Using Simon's suggestion...
Cleaned up.
fixes:

* declare a few variables (Ping, Coffee)
* move one variable to an outer scope (Ping - message)
* auto-gen documentation
* fix project file copying non-existent file to output dir causing errors on build
