Implementing custom py game in Alpha Zero

[JernejHabjan]

create td2020 game with 2d grid as games like othello or connect4 are made:

• [x] limit number of actors on tile to MAX_NUM_ACOTRS_ON_TILE --- written in grid class
• [x] attack action - check if actor is in range (actionManager)
• [x] use ALL ACTIONS dictionary to map actions to numbers or other way around (actionManager)
• [x] display_obj- make prefix of which team the piece is on board. If pieces of both teams are on same tile, make special suffix.. (Grid)
• [x] spawn new character in appropriate world - construct_unit (Components)
• [x] manager game_logic - actions are chosen as many times as current player has actors and action is random (Game)
• [x] Fix main functions like getNextState, getValidMoves... (Game)
• [x] create your action input for Human Player (OthelloPlayers)
• [x] increment health - to cover whole 100% when built to max - same as sc2 - continue building (ActionManager)
• [x] Fix input size for fit function
• [x] Fix general model sizes
• [x] Add layers to model?
• [x] in file NNet.py - i'm removing last entry in PIS - this may be wrong
