Folder memory card support

[sotpapathe]

PCSX2 now supports memory cards stored in a folder hierarchy instead of a .ps2 file. From what I have seen, the folder hierarchy is similar to the internal structure of the .ps2 files. Hopefully adding the ability to view and edit memory cards stored as folders will not be too hard to implement.

This would be nice to have, hopefully it gets added sometime in the future.
