First commit of the AuReiNand rewrite!

- Gotten rid of the patched FIRMs, AuReiNand now finds and loads all the FIRMs from CTRNAND by default. If you are booting an emuNAND, the FIRMs will be loaded from its CTRNAND. This also applies to AGB and TWL FIRM, and allows for a very fast boot with no firmware files on the SD card.
- If for some reason (like using NTR) you do not want to use the CTRNAND FIRM, you can place a firmware.bin in the aurei folder and it will be loaded just for the default NAND.
- The way AuReiNand works has changed. Now you can specify to autoboot SysNAND or not, and a NAND is no more tied to a FIRM (since 9.0 FIRM is autodetected). If you press nothing the default NAND is booted with its own FIRM, L boots the non-default NAND with its own FIRM, R boots EmuNAND with the SysNAND FIRM if you picked "Updated SysNAND", and vice-versa.
- In order for AuReiNand to handle FIRM reboots, the .bin path needs to be hardcoded in the program. The default is /arm9loaderhax.bin (the AuReiNand.dat is also supported for 9.0 people). A PC tool was written to make changing the path easier.
- Bug fixes and stuff I forgot.
- Gelex is a saint.
