Better validation when config.php does not exist
Update docs and quote password
only populate legacy vars in config_to_json
drop .travis.yml config copy
remove credentials from config.php.default
Check for existance of .env instead of config.php in python scripts
legacy credential cleanup
tiny cleanups
consistent env for artisan server and artisan dusk
* Ping only device doesn't display
if os was set to something, ping os wasn't loaded and we try to get overview graphs from it.
* Fix snmp_disable device page load error
When other os is set.
* Revamp os setting loading
the only safe way to access is Config::getOsSetting()
* Remove getOsSetting fallback behavior
Most instances don't use it and it can have unexpected results Config::getOsSetting('blah', 'group') == 'librenms'
* refactor and remove unneeded load_os/loadOs calls now since getOsSetting automatically loads it.
* restore unix overview graphs, they are different
small cleanups
* fix
