- added partial support for TCOS 2.0 cards
- default card driver now tries to do a GET RESPONSE instead of SELECT FILE to detect the correct CLA byte - moved security attribute parsing from iso7816.c to card-setec.c - added some more sanity checking to sc_check_apdu - added 'debug' command line option to opensc-explorer git-svn-id: https://www.opensc-project.org/svnp/opensc/trunk@210 c6295689-39f2-0310-b995-f0e70906c6a9
