+-- Existance of the configfile will be checked, if it doesn't exist, the default values from the options table will be written in a new
+-- file, commented out. If it exits, the key/value pairs will be read, and values of keys that exist in the options table will overwrite
+-- their value. Keys that don't exist in the options table will be ignored, keys that don't exits in the config will keep their default
+-- value. The value's types will automatically be converted to the type used in the options table.
