Update 1.1.2

Added the following features:
- Pressing the spacebar on the map maker will toggle the eraser on and off. If an object placer is selected it will toggle back to that placer when spacebar is pressed again.
- The backspace key will now close the current object menu. If a sub-menu is open (such as the bed menu of the furniture menu), this will return you to the parent menu.
- Added the ability to unlock the object count allowing maps to be made with up to 1,000,000 objects. Maps larger than the 5,000 object default will not work in multiplayer, so this option should only be used for exporting larger maps for use in other programs.
