Subject: [PATCH 1/8] Archives: Change the folder layout of some archives.

This is to better represent the hardware layout, they are still aren't quite accurate, but this better and will help a bit when implementing the other archives like NAND-RO and NAND-RW

 archives.

Each archive now takes a mount point of either NAND or SDMC, and builds its own directory structure there, trying to simulate an HLE-friendly hardware layout
