crash when doing [NSDecimalNumber -decimalValue]

[jordan.breeding@…]

Not actually that useful (intValue and floatValue are much more useful), but still I didn't expect MacRuby to go down so hard:

zsh: abort /usr/local/bin/irb

It's because MacRuby doesn't read the bridge support class/method annotations.

Fixed in r25/trunk.
