Title: Add other caching solutions besides local storage to the cache read and write controls

We are writing mobile applications with OpenLayers at Pierce County WA and we have been using the CacheRead and CacheWrite controls to get the map to work even when we lose network connectivity. Local storage doesn't allow us to store as many tiles as we would like so this pull request adds a Cache class with implementations for local storage, session storage, indexdb, and websql storage.
