Accept data via Intent and pass them on to the host as keystrokes

[DanielWeigl]

Adds new functionality to the MousepadPlugin to accept data via Intent and pass them on to the host as keystrokes via the existing MousePadPlugin.PACKET_TYPE_MOUSEPAD_REQUEST PackageType

This allows other apps to send a Intent:

        Intent sendIntent = new Intent(Intent.ACTION_SEND);
        sendIntent.setType("text/keystrokes");
        sendIntent.putExtra(Intent.EXTRA_TEXT, textToSend);
        if (sendIntent.resolveActivity(this.context.getPackageManager()) != null) {
            this.context.startActivity(sendIntent);
        }

which then shows a confirm dialog and allows to pass the text as keystrokes to the host.
The confirm dialog also has the option to white-list a sending application (by its package name) and allow it to send without confirmation.

This could be used by other apps like password managers or OTP Tools to easily send the code to the desktop.

Im open for comments/feedback in general and especial on the idea of the Intent.ACTION_SEND with mime type text/keystrokes. Somehow it feels a bit like a hack, but on the other hand i think its a quite general way, that other apps could also implement and then the Android Intent-Chooser allows the user to easily select the app he wants to use to send the keystrokes

Hi, this is actually just a mirror, so I think you'd be better off sending a merge request on GitLab (https://invent.kde.org/network/kdeconnect-android).
