caching requests

[kylemac]

to avoid unnecessary network requests (and therefore contentful "bandwidth", which is limited depending on the amount of $ you pay) – we should cache the locals in-between "watch" compiles. to pull down fresh content that may have been edited since your last compile, you'll need to stop the watcher.

this configuration should be true by default, but overridden by cache: false in your extension config.
