Move themes and version into rustdoc-vars

Browse source 
We had been injecting the list of themes and the rustdoc version into
main.js by rewriting it at doc generation time. By avoiding this
rewrite, we can make it easier to edit main.js without regenerating all
the docs.

Added a more convenient accessor for rustdoc-vars.

Changed storage.js to not rely on resourcesSuffix. It could in theory
use rustdoc-vars, but because rustdoc-vars is at the end of the HTML,
it's not available when storage.js runs (very early in page load).
