DHCP server should be disabled for /31 and /32
Related forum thread: https://forum.pfsense.org/index.php?topic=121105.0
- disable the enable DHCP server checkbox when there's a /31 or /32 "subnet" configured on an interface
- do not allow saving /31 or /32 on an interface until the user has disabled the DHCP server there (or automatically disable it on save)

It now doesn't enable dhcp on a /31 or /32 subnet, IMO the message "The DHCP Server can only be enabled on interfaces configured with a static IPv4 address. This system has none." could be worded a bit better as there is IPv4 enabled on the subnets, there is just not enough address space to assign DHCP addresses.
