Links to help from bblinks in post, edit, quickpost and signature form

Discovered that the bblink ul in the edit form contained invalid HTML. When I checked the different forms was the bblink ul not consistent in the different forms. So I decided to make it consistent over the different forms.

* If the label is green will it link to the corresponding section in the help.
* If the label is red, will it not link.
* Added some javascript, so bootstrap tabs can be activated from off page links. This to show the correct tab on the help when linking.
