Subject: [PATCH] CHG:  'hf iclass decrypt'  - adjusted the loops, to only
 decrypt Application 1.  However I've noticed not all blocks in Application 1
 is encrypted. :/  Still needs to be adjusted. CHG: 'hf iclass reader'  -
 added some output accessrights from the CopyReader source code.

And ofcourse,  moved around stuff,  like the usages in cmdhficlass.c
