Shop, new visuals and hud's

During this iteration we've made great progress and have already implemented most of the features we had in mind at the start of the project. 

The most clear change is the visual elements, we added a HUD element to display player info, new fonts, new unit sprites, board and more visually appealing background, these changes really make me feel this more like a finished game rather than some school project.

Also in terms of new systems, we've implemented the shop, so while in the preparation stage, players can add new pieces to their side by selecting them from the shop. Also there is now a way to gain new skills/upgrades,  by adding a screen at the end of a match that allows the player to select a new skill from a randomly generated batch.

On the next iteration we will be focusing in adding more skills to the game, add units, define unit movement at their different levels, and overall work on the playability aspect of the game, to ensure that pawns & legends will be an enjoyable game.
