Add ability to use IP address mask for auto-login IP range

## Is your feature request related to a problem?
**Please describe.**
Seems like the implementation/logic of autologin IP address range is weak - should be able to define ipnet with mask.
Now it just converts your IP to a long and checks if its equal to one of the ipadresses in the list(converted to long) or greater/less than the adresses(converted to long) in the provided range.
