scd: Add heuristics to identify cardtype.

Browse Source 
* scd/app-common.h (cardtype_t): Add CARDTYPE_GNUK and
CARDTYPE_ZEITCONTROL.
* scd/app.c (strcardtype): Handle CARDTYPE_GNUK and
CARDTYPE_ZEITCONTROL.
(app_new_register): Detect Gnuk and Zeit Control implementation
by examining its ATR string.
