include IITC in the app’s resources and load it from there

IITC can only be updated with the app from now on, as the remote-loading
code has been removed. The new injection method intercepts all resources
being requested by the web page and either injects our code or and empty
string. This should stop IITCM from requesting them at all, saving band-
width and reducing the boot up time dramatically.
