* 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
* Migrate devices.inserted to allow null values and set existng row values to null

* Don't display any date that stats with a zero
* make schema match migration
* Add inserted column to devices table
* Added schema for devices.inserted
* Show when a device was added and last discovered
* Added collection rule for "Device added within the last 60 minutes"

Affects nginx users:
Moved php files outside of public html directory (Apache was protected by .htaccess)

Some files did not check for authentication and could disclose some info.
Better checks before including files from user input
