Rename, was config___template.php & array rename

As we now have 2 files beginning config___, be more specific about what
this relates to
Also renamed the array to $ICEcoderUserSettings
Added config settings file

These were buried in the settings.php file, now pulled out of the file
and put into their own array
This is so they can be found easier
Load system and user settings files

$configSettings is a seperate file now, containing the array of settings
we have buried in this file
Renamed user template, so change of filename here
Also using $configUsersTemplate to be clearer about things
