* Add references to Qt Quick Layouts
* Don't lie about that Positioners can resize the items
* Rename title from "Item Layouts" to "Item Positioners" to avoid
  confusion with Qt Quick Layouts

window example: show only the splash screen until the timeout

The window takes time to resize itself; we can avoid letting the user
see that by delaying visibility of the main window.

Fix various bugs in calqlatr

It's still not a great example but at least it's somewhat usable now.
- added files to .pro so you see them all in Creator
- keypad is fixed size and the "tape" takes up the rest, so you can
  resize the window to be able to see long numbers
- you can flick the ListView (MouseArea not on top of the whole thing!)
- ListView scrolls to the bottom when you add numbers past the point
  that scrolling is necessary to see them
- Clear, sqrt and +/- keys are functional
