/****************************************************************************
Fast key cache for main game loop
****************************************************************************/
/* This is faster than using getKeySetting with the tradeoff that functions
* using it must make sure that it's initialised before using it and there is
* no error handling (for example bounds checking). This is really intended for
* use only in the main running loop of the client (the_game()) where the faster
* (up to 10x faster) key lookup is an asset. Other parts of the codebase
* (e.g. formspecs) should continue using getKeySetting().
