A simple viewer for the Signed Certificate Timestamps.
This is modeled somewhat after the CollectedCookiesView.

There are two main components introduced:
* SignedCertificateTimestampInfoView: A grid layout for showing the details of a single SCT. That's where translation of numeric fields to names happens.
* SignedCertificateTimestampsViews is the dialogue itself, containing a SignedCertificateTimestampInfoView and a combo-box listing all SCTs available. This is also a grid layout with two padding columns. 

Additionally, a function for translating between SCT ids and actual SCTs (ShowSignedCertificateTimestampsViewerByIds) was  added in signed_certificate_timestamps_viewer.h.

Please ignore the changes under net - I am having them reviewed in a separate patch.
