Version 0.4 - Player Stats

Yesterday itch.io was down and I was at the Microsoft #InsiderDevTour so I didn't get to update the game much.

The main focus of this update was adding information about the player's health, energy and score and remembering the last directory you gave so you can repeat replays.

* Added player health, energy and score

* Show the name of the bot on the map
* Made the explosion particles semi-transparent so you can see better
* Minor changes to the models so you can see the different building types clearer
* Start screen now remembers your last path making replay easier
* Turned off the camera height reset because it was stupid
