Certificate Transparency: Improving Signed Certificate Timestamps viewer

Improved the SCT viewer according to review comments in the following
ways:
* Using labels rather than textfields for data display. This allows
  splitting the Log ID and Signature Data fields over multiple lines
  in a non-ugly way.
* Enabling internationalization of the Combobox text by using
  GetStringFUTF16.
* Improving the string used in the website settings bubble.
* Finally, removing the flag to enable the viewer.

PNaCl documentation: link to ARM 32-bit sandbox internals

The new developer.chrome.com site navigation doesn't go more than 3
levels deep. We must go deeper. The sandbox internals index page now
points at the ARM 32-bit document, and also lists the other sandboxes
(which we should write about at some point).
