Add Resource tracking to Map Singleton

[krogenth]

We'll want to keep track of what resources are on the game map and where they are located. For Map initialization, we will want to retrieve and store all Minerals and Geysers in the match. To do this, we can use BWAPI::Game::getStaticMinerals and BWAPI::Game::getStaticGeysers to retrieve the full listing of resources.

For Mineral patches that we cannot see, we may not get an event trigger of that Mineral patch being mined out. Though it should be a very low probability that we take a base another player has mined out or used in general.
