Guillaume Borios fixed bug #508

When unicode translation is ON, pressing the escape key raise an NSBeep()
because the NSTextView interprets the key as a special command (in that case
impossible to interpret)... The NSTextView instance should replaced by
something subclassed so that doCommandBySelector: does nothing.

Example code :

@interface SDLTranslatorResponder : NSTextView
{
}
- (void) doCommandBySelector:(SEL)myselector;
@end

@implementation SDLTranslatorResponder
- (void) doCommandBySelector:(SEL) myselector {}
@end
