added start of dhcp fallback. Also, removed %t as a tab string match char... that does not exist... why did I think it did? I honestly don't know. But, now I have to go search all my other string match functions to make sure it is not creeping in all over.
clients status page now (see last commit as well)  checks if nodogsplash is enabled and will fall back to dhcp.leases as info source if it is disabled.
