Fixed : disabled keylogging and debugging in AHK scripts for better privacy and security

[pieter-degroote]

New for release r2020-06-27 :

The keylogging and debugging (only in memory, during the active session) has now been disabled for better privacy and security.

It is highly recommended to switch to release r2020-06-27 (or later), or to add the following two lines at the top of an earlier version :

ListLines Off  ; omits recently executed lines from history (for privacy and security)
#KeyHistory 0  ; disables the key history (for privacy and security)

This is especially important for public places, like schools and libraries, to avoid spying/snooping !
Apart from that, other privacy/security measures might also be necessary.

Release r2020-06-28 also deletes the content of the 'key' variable afterwards to avoid leaking its content via debug properties.
