Bugs:

Fixed Firmware download from the Mikrotik website when there are multiple npk available
Fixed Mikrowizard system permission error when it is set to None
Fixed user device group permissions
Some minor UI improvements
Fix IP scan for one IP scan / Fix not scanning the last IP in the range
Fix manual snippet execution not working when device groups are selected
Some minor bug fixes and improvements
