Bring back Custom Logo

[sgr78]

Since v1.0.1070
with the Implementation of: opt.: hide logo if distribution == null by @lollipopkit in #536
Custom logos are NOT always displayed If distribution is not on the list.
Many colleagues of mine and Including me were able to freely set Custom logo to each Linux Instance as to easily distinguish It by Its use, e.g. on the Grommunio Linux Instance we put a Mailbox Picture, on the VPN Linux Instance we put a Custom picture and so on.
Imagine having five or ten Instances/Servers and the only picture allowed to be ONLY the distro Icon, this is not helpful when managing
many machines.
Please bring back Custom Logo Icon as it was Implemented on v1.0.1051 and before, don't narrow option to ONLY distro Icon..

Thanks!
