Use direct lookup in showImages (rather than looping through)

First attempt at a hash based solution for loading site modules. Rather than looping through all available modules until a detect matches, this version should now use the `domainToModuleName ` method to programmatically figure out the modules name. (Similar to the HB's betterzoom)

In order to get this working I've had to make a few minor tweaks.

* go() has been removed (mostly as nothing appeared to using this)
* A few modules have changed names in order to match their hash lookups ("bac.on" with this approach would need the name "bac")
* Add support for alias's for sites that utilize multiple domains (so far this just youtube)
* support for 2 part tld's exists, but I've commented it out for now as its not currently needed.

Whats everyones thoughts?
