Implement "Email Link To Page" menu command.

This menu item only exists in the Mac build, but the code is cross-platform so it could be hooked up on other platforms as well, if desired.
It works by generating a URL of the form
  mailto:?subject=Fwd:%20PAGETITLE&body=%0A%0APAGEURL
and telling platform_utils to open it.

This is my first patch involving command handling; I've tried to follow the way similar menu commands
like Print are implemented, but feel free to tell me if there are better ways.

I didn't find any place for unit tests for TabContents; if this needs tests, let me know where they should go.

BUG=29232
TEST=none
