nit: avoid overloading the non-virtual base class method name.

I can come up with any other random name (e.g. Initialize()), but Init() seems
to be the most typical?
Note that this also hides the base class declaration and cannot be called
without explicit name qualification.

I'm fine with either.

Consider CertificateSelector::InitAndShow, since it also triggers the dialog to
actually be shown (which is rather odd for an Init function).

It'd be nice if Init was just rolled into the ctor (with a new text arg) and
chrome::ShowSSLClientCertificateSelector called
constrained_window::ShowWebModalDialogViews explicitly, but then I guess
something else would need to select the first row of the table to start, if that
actually needs to be done after the dialog is created/shown.

I considered the splitting as well. It makes the Init() behave more as expected
but that doesn't help with the overriding.

Regarding putting the initialization into the c'tor, I think that is more
harmful than good in C++, also the style guide explicitly disallows that:

"Avoid doing complex initialization in constructors (in particular,
initialization that can fail or that requires virtual method calls)."

I renamed the Init function in the base class to InitWithText and made it
protected.
