* added code and tooltips to custom site feedback
- clarifying that the feedback widget needs to be turned on
- showing how to disable the form and
- show the notes that are configured
* undoing a minor change that we unnecessary
- I changed a colon to a full stop at some point because I thought I
would add another sentence, decided not to and then the unneeded
change ended up in the previous commit.
* turned a comment I deleted into a tooltip
