* src/gig.cpp, src/gig.h: added ReadAndLoop() method to class 'Sample'
  which is an extension to the normal Read() method to honor the sample's
  looping information while streaming from disk
* src/RIFF.cpp: minor fix in Chunk::Read() method (only a minor efficiency
  issue)
* src/gigdump.cpp: added printout of samples' looping informations
