BIND9 slave configuration

[kristoff-it]

When using the BIND9 Integration, the procedure to add a slave configuration is not complete.

What happens now:

1. you add a new zone
2. when you select the type you only get master as a choice but you can type slave manually
3. you select where to place the zonefile
4. you get a textarea with a stubbed zonefile inside

What I believe should happen:

1. you add a new zone
2. you select slave
3. you are prompted for one or more master ip addresses
4. you select where to place the zonefile (5. you don't get the stubbed textarea)

This should probably not be a prioritized feature since one can easily add the zone manually without breaking anything.

I just noticed the bind9 integration is a ajenti plugin, my bad. Closing and opening the same issue in the correct repo.
