Add chrome.webstore API methods to allow sites to see progress of installation
Add two chrome.webstore API methods for progress updates:
chrome.webstore.setInstallStageListener(function(string stage))
- stage is either "downloading" or "installing"
chrome.webstore.setDownloadProgressListener(function(int percent_downloaded))
Update InstallObserver to have methods for install stages.
Make WebstoreInstaller provide more frequent download updates (current consumers
like WebstoreResult imply this was intended from the start).
