ChromeUpdater in my flavor

In fact, I'd like to call it ChromiumUpdater.

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. Syntax:Updater.bat
BUILD_NUMBER
4.Automatically install the package using 7-zip.
5.Download the changelog as well.

By default, the Chromium will be installed in C:\Program Files
(x86)\chrome-win32.

Seems enough?
