Updates to the country code list, based on the current scene releases.

(NOTE: Not sure if I should change D to NOE instead of GER.)
Added functionality to strip SWAVs from SWARs.

Additionally:
* Removed the references to INFOEntry* data from the SBNK/SSEQ/SWAR
classes (while it wasn't a lot of data to copy around, it is still a
waste of memory in the end).
* Used unique_ptr of SWAV instead of an instance on the SWARs.
* Fixed a few issues in the SBNK stripping.
* Used some typedefs when possible.
* Fixed unsigned underflow with a loop offset of 0 on an ADPCM SWAV.
* Updated version numbers and README.
* Other minor cleanups.
Corrected issue with binary comparison of SSEQ data failing due to the SBNK stripping.
