opensc-explorer: convert do_info() to using tables 

* use ID<->name tables instead of arrays of strings where
  the index was treated like some "magic" constant.
  With the new mapping tables, the meaning is obvious.

* fix a bug with ac_ops_df[]: before the conversion, it was a list
  of pointers to strings but was in one case treated like it was a mapping table.
  With the conversion to a mapping table, and the adaption of other code parts
  this bug got fixed "automagically" ;-)

* use common code to cleanly print ACLs for DFs & EFs

* harmonize EF structure names to the ones used in ISO 7816-4
