Make chrome.exe read version from Software\Chromium instead of Google Update keys when running Chromium. With this change
now we can build a Chromium release that gets installed under Application Data\Chromium and actually runs.
- Added a new file that has common functions used by google update client and chromium
- Did some minor cleanup based on readability guidelines (alphabatical order etc).
- We seem to be trying to avoid std::wstring at some places but are using it at other places. In future we should be just able to use std::wstring and get rid of StringCchDup.
