Subject: Docs: GridMap and MeshLibrary

The only methods left to document are resource_changed, set_clip, and
the methods dealing with baked meshes.

-		GridMap lets you place meshes on a grid interactively. It works both from the editor and can help you create in-game level editors.
-		GridMaps use a [MeshLibrary] which contain a list of tiles: meshes with materials plus optional collisions and extra elements.
-		A GridMap contains a collection of cells. Each grid cell refers to a [MeshLibrary] item. All cells in the map have the same dimensions.
-		A GridMap is split into a sparse collection of octants for efficient rendering and physics processing. Every octant has the same dimensions and can contain several cells.
