Firefox 2.0 Updates

Both of my extensions have been updated to work with the new version of Firefox (2.0). No functionality changes have been added, just a compatibility update, so look in the next few weeks for a new version of Chinesepera-kun with some much needed changes and possibly an updated Perapera-kun (Japanese) with a few bug fixes/updates a couple people wanted.

Perapera-kun (Japanese) 0.5.22
Chinesepera-kun 0.2.0
