Save the capture settings on launch, offer button to load most recent

* This gives a one-click way to run the last capture, if it's not
  complex/regular enough to be worth saving to a settings file on its own.
* Doesn't save much if you're selecting an exe as the previous exe location is
  remembered, but if you also have command line parameters or a working
  directory it can help.
