Fix: SSH-Verbindung scheiterte an Key-Exchange-Aushandlung mit RouterOS

Browse Source 
RouterOS' SSH-Server bietet typischerweise nur ältere Algorithmen an
(diffie-hellman-group14-sha1, RSA-Hostkeys), die in Citadels
Standard-Algorithmenliste fehlen -> keyExchangeNegotiationFailure beim
Verbindungstest gegen echtes Gerät. Citadels vorgefertigtes
SSHAlgorithms.all-Preset aktiviert diese Legacy-Algorithmen.
