/**
* Settings-macro usage:
* The list might look daunting at first, but is in general easy to understand.
* The macros can be grouped depending on where the config variable is
* stored:
* 1. SDTG_something
* These are for global variables, so this is the one you will use
* for a #SettingDescGlobVarList section. Here 'var' refers to a
* global variable.
* 2. SDTC_something
* These are for client-only variables. Here the 'var' refers to an
* entry inside _settings_client.
* 3. SDT_something
* Thse are for members in the struct described by the current
* #SettingDesc list / .ini file. Here, 'base' specifies type of the
* struct while 'var' points out the member of the struct (the actual
* struct to store it in is implicitely defined by the #SettingDesc
* list / .ini file preamble the entry is in).
*
* The something part defines the type of variable to store. There are a
* lot of types. Easy ones are:
* - VAR: any number type, 'type' field specifies what number. eg int8 or uint32
* - BOOL: a boolean number type
* - STR: a string or character. 'type' field specifies what string. Normal, string, or quoted
* A bit more difficult to use are MMANY (meaning ManyOfMany) and OMANY (OneOfMany)
* These are actually normal numbers, only bitmasked. In MMANY several bits can
* be set, in the other only one.
* If nothing fits you, you can use the GENERAL macros, but it exposes the
* internal structure somewhat so it needs a little looking. There are _NULL()
* macros as well, these fill up space so you can add more settings there (in
* place) and you DON'T have to increase the savegame version.
*
* While reading values from openttd.cfg, some values may not be converted
* properly, for any kind of reasons. In order to allow a process of self-cleaning
* mechanism, a callback procedure is made available. You will have to supply the function, which
* will work on a string, one function per setting. And of course, enable the callback param
* on the appropriate macro.
