Update 0.1.3

This update is a great but small update, and takes us 1 step closer to the completion of the game.

The implementation of textures in the room files allows me to easily change and replace the textures on walls and floors with ease. This is going to be very useful in the future when I make the graphics match with the models and look good, but for know you may have to deal with some stretched out textures and no normal maps :(

I have also added the ability to right click and drop items, with the item interact button being changed to the left mouse button.

I hope you enjoy this update and continue to escape!
