v0.1.3: Player Inventory

Hello and welcome back.

I have changed the game's font. I don't love it, but I think it's an improvement over the default. As with all other assets in the game, this is a prototype and will be changed later.

I have added a GUI element to show the player the upgrades they have purchased. This is displayed at the bottom of the shop screen for now, but expect it to also appear in the Pause menu when I implement that.

The items in the inventory have tooltips -- when you hover over one with your mouse, it will display the upgrade name and your current total bonus. I am aware the tooltip font is not the same as the font in the rest of the game, but I am figuring this out soon! I also have an item on my roadmap to add more upgrade icons so that each upgrade has a unique image, or at least unique border.
