Bukkit

Small features and other improvements
- Panel close commands no longer run on panel refreshes
- Language file (lang.yml) can now be regenerated on reload, not just server restarts
- [item] tag will now return a pass if item amount required is 0 as expected
- Using `-s` in the /pa open command will now silence plugin responses (useful to keep console logs clear)
- Newline can now be used in item lores for new lines
