[Closed] New Resources System

[bensch]

The old ResourceManager was suffering from some major drawbacks: Whenever a resource was loaded you had to unload it manually with ResourceManager::unload(). It was also extremely complicated to extend the ResourceManager with a new ResourceType.
Furthermore there were minor issues of typesafety and performance issues.

The new implementation is more modular, easily extendable and more intuitive to use for a programmer.
