Prepare future controlpanel
Add xdash namespaces dashbpard package

We copy the overloaded seodash package and refactor some of the
contents to be more streamlined and easiier to handle.

Things that will most likely be changed:

- reports will move to xdash.reporting
- dashboard manager will move from seotool package
Add linkbuilding view and refactor

We provide a preformatted JSON file for better data manipulation
Return valid json on import

The template and several dynamic components involved in the report
generation need to make sure we actually build correct files
Rebuild link buildout table view
Update report builder
Update ga setup and report json template
Pass query type to ga requests
Modernize the frontend and refactor
