/** @file settings.cpp
* All actions handling saving and loading of the settings/configuration goes on in this file.
* The file consists of three parts:
*
* - Parsing the configuration file (openttd.cfg). This is achieved with the ini_ functions which
* handle various types, such as normal 'key = value' pairs, lists and value combinations of
* lists, strings, integers, 'bit'-masks and element selections.
*
- Handle reading and writing to the setting-structures from inside the game either from
* the console for example or through the gui with CMD_ functions.
*
- Handle saving/loading of the PATS chunk inside the savegame.
