[Feature Request] Extreme Space Cadet configuration

[AdamNorberg]

Description

By redefining LSPO_KEYS, RSPC_KEYS, LCPO_KEYS, RCPC_KEYS, LAPO_KEYS, AND RAPC_KEYS in config.h, it's possible to create an Extreme Space Cadet configuration where Shift, Ctrl, Alt, and GUI each emit a different bracket character (as long as GUI gets square brackets -- the only unshifted bracket character -- using MT(MOD_LGUI, KC_LBRC) and MT(MOD_RGUI, KC_RBRC)). However, the Configurator doesn't seem to provide any way to override the key codes generated by the Space Cadet keyboard commands. (It will allow the illegal MT(MOD_LALT, KC_LCBR) and similar to be specified, but these will lose the shift key in practice.)

Some way to specify these in the Configurator would let me use the key configuration I'd like without having to puzzle through the generated code and find where to patch a config.h file.
