* refactor: convert validations to modules to prep for gui integration * accidentally dropped, schema update * fix accidental output to webui * mention discovery-wrapper.py and re-arrange. * refine some fix statements * rename the Config validation group to Configuration. * fix some scrutinizer issues remove as many local functions from validator.php as possible move extensions from pre-check remove duplicate timezone check looks like there is some db schema differences between mariadb 10.1 and 10.2, investigating * mariadb version diff take2 * Check schema version first for database. Remove stop to go back to command line for install docs. Add helpful link when there is no devices added to /addhost * fix incorrect validation for empty string defaults * Fix style * Add additional file permissions checks * catch exception and fail for invalid timezone Change visuals a bit. * add php version warning * fix space
