Changes between Initial Version and Version 1 of Ticket #4450, comment 1

initial	v1
12	12	* CMapSummaryReader tries to change the extension of the path to ".xml" [source:ps/trunk/source/graphics/MapReader.cpp#L341]
13	13	* to change the extension VfsPath gets the Basename
14		* To get the basename it of course chops off the ~~extension. It thinks anything after the `.` is the extension, so~~ the new path is just `.xml` without any name, which of course does not exist.
	14	* To get the basename it of course chops off the current extension and then adds the new one. It thinks anything after the `.` is the extension and removes everything past it. Thus the new path is just `.xml` without any name, which of course does not exist.
15	15
16	16	Even if we don't support periods in filenames, if the game fails to load a map it should just not include the map in the maps the player can choose from instead of hanging in the loading screen.
