Add "EUROPE" config define? about pokeruby

[camthesaxman]

I think the route we're going with now is to have a #define for each bug fix, and selectively enable them in config.h, and the actual code just uses #ifdef BUGFIX_SOMEBUGFIX instead of checking the language. It doesn't seem any more verbose to do something like this:

#if GERMAN || FRENCH || ITALIAN || SPANISH
#define BUGFIX_SAVEFAILEDSCREEN2
#define BUGFIX_TRAINERAPPROACH
#define BUGFIX_FOO
#define BUGFIX_BAR
//etc
#endif

UI-wise, I expect there to be a METRIC/IMPERIAL define as well, ultimately.
