Add Smartcard functions (RDV4.0) (#646)

* allow common makefile options-defines

* remove non-existing file references

* Uncomment lcd option (still) not enabled by default

use Makefile_Enabled_Options.common
to enable lcd if desired.

* Add Smartcard Functions

* add smartcard to menu + make get atr work

sc is now functioning as far as my limited knowledge takes me

* sc cleanup - add init to all sc commands...

because cmds won't work until the first init happens.  (multiple inits
don't appear to affect it negatively)

* default options to exclude Smartcard

for main repo

* update changelog

client/cmdmain.c
