Basic first-run page
First run controller: post to /admin/init on submit
Once org is initialized, display info
"Clear master key" button
Auto trim master key from response (get rid of `"`)
When org is not setup, autoredirect to FirstRun page
No need for `InstallScript` anymore
Fix condition
Perform `/admin/init` call via AJAX and reload when done
Clearer success message
Add test class for FirstRun
