Allow Space Cadet state to be canceled by alternate Shift key

Allows you to press RSHIFT to cancel the insertion of a "(" when holding down LSHIFT. Alternatively, allows you to press LSHIFT to cancel the insertion of a ")" when holding down RSHIFT. This change enables you to renege from outputting a character should you press a shift key erroneously.
