A method to specify that a sensitive entry should not go to the history

[zefr0x]

Some times we need to copy sensitive data like when using a password manager. In those cases we need a standard way to tell Clipcat that this entry should not go to the history.
Turning off clipcatd temporary or deleting the entry manualy is not a sulotion.

The best way to do that is using mime-type.
The clipborad holds a mime-type along with the content in order to differentiate between contents data types like text, images or videos...

For example the Klipper clipborad manager uses x-kde-passwordManagerHint as implemented here. And the KeePassXC password manager is making use of that here: keepassxreboot/keepassxc#1969

Thanks for the proposal.
The pull request #170, #139 might solve this issue.
Sensitive content could be detected by clipcatd now.
The hint such as x-kde-passwordManagerHint could be passed from configuration watcher.sensitive_x11_atoms. clipcatd ignores the clip once one of the X11 atoms listed in sensitive_x11_atoms is matched, the sensitive contents are ignored, they will not be shown on the list, history, log message.

The new features will be introduced in the next release.
