Core gameplay loop

Today marks the release of the first complete gameplay loop of the game. The following mechanics should be stable:

• Player choosing a side each time, starting as blue.
• Units are correctly moving in each phase: move, attack, boost and display the appropriate preview for side that will move first.
• The game is organized in rounds, which have turns that increase the number of points each side has. When one of the sides wins, the player is prompted to change one unit of the winning side. Afterward, the game restarts with the new unit.
