[Coco] Mocha emulator working now

[Roger Taylor]

All this time somehow a checkbox was cleared in my internet options 
which caused some Java stuff to not work.  I overlooked this many times.

Anyway, it's too nice to see the Mocha site pop up with a CoCo 
again.  I think the author deserves a huge round of applauase for 
doing this in Java with so many ready games in the menus.
