ConfigurO 2.9

Fixes

• Setup no longer installs ConfigurO onto a PC that cannot run it. Microsoft's
  .NET Framework installer returns success without installing anything when it
  decides it cannot proceed -- an edition it does not support, an architecture it
  does not carry, a restart already pending. Setup took that at face value, copied
  ConfigurO into Program Files, made a Start menu shortcut and launched it, so the
  first thing you saw was Windows refusing to start it and a setup that had
  reported nothing wrong. It now checks that the framework is actually present
  and says so plainly if it is not.
• Hint text in every input field is visible for the first time. The hints were
  drawn on the frame behind the field rather than in it, so all eight of them --
  on Hosts, Integrator, Network and the tweak search -- had never once appeared.
• The "Flush DNS cache" button showed "Flush DNS cac". It and the line beside it
  were sharing a 320px column that fits neither; they now sit one above the other.
• Buttons that had a fixed width now measure their own label, so "Block",
  "Download" and "Flush DNS cache" cannot be cut off in any language.
• The Hardware screen no longer reports "@ 0 Hz" when Windows will not say what
  the refresh rate is; it leaves the rate off instead.
