--- Automagical config handling
--- options:     A table with options setable via config with assigned default values. The type of the default values is important for
---              converting the values read from the config file back. Do not use "nil" as a default value!
--- identifier:  A simple indentifier string for the config file. Make sure this doesn't collide with other scripts.
-
--- How does it work:
--- 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.
