After a mapping change (e.g. the parent-child restructure), existing installs
need to rebuild their index. A DashboardWidget appears on the admin page
warning the admin and showing the command to run. Compatibility is tracked
via the blomstra-search.index-compatible setting.
The flag-based interface (--rebuild etc) became rather convoluted with the changes. Replace this with commands with more straight forward naming.
Also added an explicit 'rollback' action and updated the README.md
