Require fix on MDVRHeader.h

[Spettacolo83]

Can you fix a define line from:

#define MDVR_RAW_PATH [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: MDVR_RAW_NAME]

to:

#define MDVR_RAW_PATH [[[NSBundle bundleForClass: [self class]] resourcePath] stringByAppendingPathComponent: MDVR_RAW_NAME]

With this modification, my 360 jpg viewer now works correctly!
