Add banlist module and fix jquery map error in Chrome

Adds a banlist tools module, based on my banlist live filter userscript: https://gist.github.com/Dakta/9176377. Includes toggle module on/off.

Fixes an error where Chrome would look for a missing jquery*.min.map file and throw an error about external resource access. This adds the missing file and adds it to the external resources list to remove the error.
