GUI interaction tests #19
Description
Tests that run "GUI.ProcessClick" on various controls, and assert that controls have reacted properly:
- buttons performed their click function,
- listbox changed selection
- slider changed value
Test for TextBox reacting to Game.SimulateKeyPress.
Tests that emulate moving mouse cursor (by changing position), and assert that buttons change their state when the mouse is over them.

Unfortunately, it seems impossible to test button's push state, because there's no way to set mouse key state to "down", only do a complete "click" simulation.
