Fix 1955: Show Chromium build number after version (Chromium only)
Fix 1955: Show Chromium build number after version (Chromium only)

People download random builds of Chromium off our server. This makes it easier
for them to figure out what build number they are using by showing it in the 
About box (in parenthesis right after the version number).

This change does not change the way we display versions in Google Chrome.
