Live Reload testmode plugins

Right now debugging plugins that are in testmode is rather tedious since you have to:

  • Diagnose and fix the issue
  • Uninstall the old version
  • Install the new version
  • Sync from bot settings just to be safe
  • Reload Discord
  • Realize there’s another issue

This would basically make it just like if the plugin was unpacked and you were editing that.
