My version of ChromeUpdater

In fact, I'd like to call it ChromiumUploader
Changes:
1.Create Update.log which is more than LATEST_CHANGE
2.Download chrome-win32.zip instead of mini_installer.exe. No registry
writing. No desktop shortcut.  No nonsense.
3.Manually update from a specific build number: Updater.bat BUILD_NUMBER
4.Automatically install the package using 7-zip.
5.Download the changelog as well.

Seems enough?
