Show and edit database descriptions

[bsteubing]

It would be great to show and edit database descriptions in the AB. Sometimes special knowledge is needed to understand a specific database and how it is modelled, etc. I have not checked in detail now how this work in bw (but I think it exists) and it would be great to give the user the possibility to access and modify this information starting from the databases table. Maybe @cmutel has more specific ideas on this, if not maybe good for you to listen along here.
