QtNetwork (examples) - update secure socket client example

This patch contains:

- some cosmetic changes to  make example look more like
  modern C++;
- UI initialization code and SSL signals handling were split
  into separate member-functions;
- useless checks 'if (socket)' were deleted;
- widget's minimum size is now fixed + font size
  in 'CertInfo' dialog increased to make it readable.
