Improve UX of grid selection dialog
This fixes UI drawing quirks on Windows and improves the margins. It also adds a descriptive text on how to use the dialog. It adjusts the cursor position when changing the size via keyboard so switches between keyboard and mouse usage of the dialog are fluid. Test-Information: Verified usage and looks on Windows 8 with Qt 5.4.2 and on OS X 10.11.6 with Qt 5.5.1. Change-Id: I983656d7d08d49ac4914380ae42ed5ce49fcea12
