Switches to US English (colour -> color).
This includes replacing generated/en.js with generated/en_us.js and
changing the generation process described in comments at the start of
template.soy.

Also fixes bugs:
- Fixes scoring bug by adding return value to Turtle.checkRequiredColours().
- Fixes URL bug by adding page to URL from interstitial.
- Eliminates mysterious level failures by removing 'while' from BlocklyApps.REQUIRED_BLOCKS.  ('while' never occurs in generated code.)
