Beta Update R2

Hi all, this plugin has been updated to version Beta R2 today 🎉!

This update fixes a bug with the map name window still opening if it was blank if it was set to show the windowskin. I also updated the plugin to warn in the dev tools console instead of crash when it detects invalid JSON parameters (for example, if one of your presets is invalid).

Beta R2:

• Fix bug with map name window opening if it was set to show the windowskin
• Now warns in dev tool console instead of crash when invalid JSON detected
