0.18.4

0.18.3 -> 0.18.4

Changes:

• In order to place a unit, the unit button will need to be selected every time.
• Once the unit is placed, the button will become unselected.
• When selected, it is possible to unselect the button by clicking it again.
• To reveal stealth units, it is now necessary to click them with the left mouse button (as opposed to the right one previously).

The above changes were made so that it is possible to play the game with the left mouse button alone. This also enables mobile play. While the full mobile support is still not implemented, this should get us closer to having it at some point.
