janwas 6cc0b1649a robustified GetPatch / GetTile:
- clarify the meaning of mapSize (patchesPerSide)
- use a single ClampCoordToMap function for clamping
- add annotations to all call sites when it is sure they will succeed
- otherwise, ensure return value is checked or at least add debug_assert
fixes #311 (successfully built house and dock at top of latium map)
thanks to Heron for tracking down the cause!

This was SVN commit r7183.
