Remove chrome.sync data on install, so that no stale directory entries are retained (retainEntry method in chrome.fileSystem api)
Added an internal utility feature that will find out the id of the live development extension.

This is necessary because if you are in development mode, then chrome will generate a new id for the extension and therefore we have no way of knowing what the id will be. This isn't an issue on the chrome store since the ids are static.
