Change cursor icon on hovering over different UI elements

[PUFFMON]

Description

When playing using keyboard and Mouse, the mouse cursor's icon will change depending on what UI element is hovering on:

• Basic menu buttons (Settings, main menu, etc) - PAINTING HAND IDC_HAND.
• Text inputs (World name and seed) - I BEAM IDC_IBEAM.
• Sliders (World size and some settings) - RESIZE HORIZONTAL IDC_SIZEWE.
• None - DEFAULT ARROW IDC_ARROW.

Changes

Previous Behavior

The cursor always used the Arrow icon.

Root Cause

The behaviour wasn't programmed.

Fix Implementation

I added a new function inside KeyboardAndMouseInput script that changes the icon of the cursor. This function is called in UIController.cpp inside tickInput.
