* fixed a crash when unloading a lua script

* added event types, foreground and background color for watchlists
* added a url_encode function to lua to encode urls. Underneath, it just
  calls the standard library function from golang
* updated the README
* the urban plugin now can take in the number of entries to return
* reverted a bug where setting the http proxy for the lua http module
  was not working
* fixed the url for the ip script so it is actually working. the current
  provider does not support ipv6 though
