Support multiple maps per mapgroup

[jbirch]

Please modify Fusion to allow multiple maps to be added to a single MapGroup?.

Currently in MapGuide you can not share tile caches among multiple maps, and modifications to the dynamic portion of a map invalidates the tile cache.

If Fusion allowed users to add both single-tile and tiled map definitions to a single MapGroup?, this would allow similar behaviour to MapGuide's current base layer groups with neither of these drawbacks.

(In [1775]) closes #140: example of mixed layer types in a MapGroup?; basic implementation of this is complete but more testing is required. Report issues as individual tickets
