Wording fixups
Wording fixups

Wording changes that (I hope) make things easier to understand.
In some places I haven't made changes even though it might make sense as I haven't had a chance to experience koalixcrm/figure out what changes are required.
I haven't installed Koalixcrm yet, only read docs and looked at the demo.
