Cache content_scripts/vimium.css in chrome.storage.local.
Previously, we had two different approaches. This seems like a simpler approach. We simply cache the Vimium CSS in chrome.storage.local (in the background page) and fetch it from there (in UI components). There is also a minor change in the we no longer cache the CSS in memory. This seems to be the right thing to do. Caching the CSS in memory consumes a small amount of memory. However, it can only speed up the fastest loads. It cannot speed up the first load -- which is likely the one that matters most. So caching the CSS in memory seems to make little sense.
