Breaks some stuff like selected dash in the search result.
In dashboard search, if the user is not searching then the result is
returned as a tree structure. No ACL's or user group ux yet.

Explains that you need to clone the grafana repo if you have not done that already.

When table data returns a column with the value 0, it should not ignore
it. This change checks for undefined instead of if the value is truthy.

Fixes #8531

To be able to build the docs an awsconfig file must exist for the Dockerfile to copy. This adds an instruction to create an empty, dummy file so that the build will work.

dashboard_history: fix for scenario where reverted dashbord has different title and url must change not just route reload

dasboard_history: fixed disabled attribute so it works both by disabling and fixing style, no need for disabled class and disabled attribute

dasboard_history: fixed json diff so only dashbord is compared and not the whole dashboard revision object (message and restoreFrom etc was showing up in json diff)

dasboard_history: big refactoring of how the compare api looked, now a POST with a model for new & base version, refactored a simplified UI code as well, this was done to lay foundation to make it possible to do diff against current in browser unsaved version

dashboard_history: further css & markup fixes, removing style overrides & resuing existing styles and markup components

dashboard_history: SQL did not work when using MySQL, fixes to dashboard version numbering, so inserts start at 1, added migration to fix old dashboards with version 0
