new version of pcsc-tools: 1.4.20

I just released a (two in fact) new version of pcsc-tools. The major change is the move of the personal litst of ATR used by ATR_analysis from ~ to ~/.cache/.

If you do not know what pcsc-tools is, it contains 4 tools:

• pcsc_scan(1) regularly scans every PC/SC reader connected to the host if a card is inserted or removed a "line" is printed.
• ATR_analysis(1) is a Perl script used to parse the smart card ATR. This script is called (by default) by pcsc_scan.
• scriptor(1) is a Perl script to send commands to a smart card using a batch file or stdin.
• gscriptor(1) the same idea as scriptor.pl(1) but with a Perl-Gtk2 GUI.

An equivalent of ATR_analysis is available online http://smartcard-atr.appspot.com/
