Alpha 2.0

Hello everyone it's been quite a few months since I've worked on the project but I've began to resume fixing and moving forward with it.

If you do try the game and have anything in particular you want to say please leave a comment.

- Fixed the path connecting problem

- Fixed being able to go negative money in some instances

- Made sure planes stopped breaking after a save and load cycle due to a state issue

 - Airports can hang off of the edge of water but now you can't place water below them by accident in naval build mode.  

 - Naval build mode only gets disabled when choosing a different tile that isn't selected in the boat menu, for the time being this is intended behavior, remember if you want to remove tiles make sure to open any other drop down menu and select a tile that is not within the boat menu to exit Naval build mode, will likely work on changing this in the future but I see it as a rather minor thing currently

 - When you give orders to a vehicle and buy it the menu won't disappear and the orders won't be cleared so that if you wish to repeat buy a vehicle on the path you just set multiple times it is easy.
