Cyan 19b426b5a7 * Fixed USB Initialization when using usbport 1
(Thanks Dimok and Dynamit)
* Fixed compiling on Linux
* Added back support for WBFS partition without a partition table
  (Thanks PontoonAdmiral for the tests)
* Fixed Wad installation on EmuNAND 
  (both file decryption and file size)
* Fixed channel's save path creation when using Emulated NAND
* DML: Added Cluster size detection
* DML: Updated DM(L) detection up to version 2.8
* DML: prevent NODISC2 patch if not using DM(L) v2.2 update2
* DEVO: Added Widescreen setting (requires Devolution r188 or newer)
* DEVO: Added AHBPROT detection
* Updated libntfs
