Yellow Flag for unlisted domains impersonating popular services
Shows a yellow header message with two buttons. "Warning: This is really where you want to be? Maybe you was looking for (link of the popular service domain). [Close] [Close & Don't show again for this site]"
Maybe add a button [Report Phishing & Go to correct site] would be cool, and then we could automatically report them to Google/Mozilla.
Also, with this function, adding at yellow-flag search domains, services such as paypal and gmail, would make this extension useful for everybody, not only ethereum users.
Would be nice to look automatically of look-a-like characters, suchs as I (uppercase i) looks like l (lowercase L), and others, such as variants with '-' and '.'.
