SetAsMetroDefaultUI -> SetAsDefaultBrowserUI or something like that

Chrome being available for metro-mode is a side effect of being the default
browser on Windows 8.  The motivation here is that a program can't become the
default browser on Windows 8+ without involving an interactive Windows Shell
dialog.  True, one reason we're jumping through these hoops is that we think the
user will enjoy using Chrome in metro mode, but technically all we're doing is
prompting the user to make Chrome their default browser.

We also explicitly restart the program in Metro mode upon success, so I thought
putting 'metro' in there would be perfectly appropriate. But...
Done.
