Version 0.7 - Pretty Update

It's been a long time since the last update. I really wasn't liking the look of Unity's lightweight graphic pipeline so I reverted to the default one.

I've also created a proper system so each building type can respond to events like being built, getting damaged and being destroyed. Already I've updated the attack buildings to animate uniquely. This will be useful in future updates when I get damage working.

I've added a basic terrain to ground the board in a world. I'm not sure if I should actually remove the board and have the buildings live on the ground like a C&C game (Let me know what you want in the comments).

Changelog:

* Added scenery to ground the board
* Implemented building events so building can have unique animations for now and future
* Updated the look of energy buildings
* Changed the building animation for attack buildings
* Fixed the floating player name text
* Reverted to the default graphics pipeline
