Showing Off Various Features

So we've made various improvements to the movement system, including fixing a lot of edger cases.
We also implemented a basic UI that will probably completely change in the near future.

• Currently it features combat text that floats away after you attack a character.
• Hero portraits that let you select a hero without clicking on a grid tile.
• An Action selection menu, appears only after moving at the moment.

Also, we added directional sprite walking animations.
Grid highlighting which shows tiles(blue) that are within the hero's movement range and tiles(red) that are within reach of your weapon.

Also ignore the random numbers.
