dhcp server RRD graph
after adding the lease_counter to status_dhcp_leases.php, i've tried to get the same data into RRD.
please check PR and if possible provide some feedback

steve_b merged the PR above.
i've further improved the graph by adding dhcp-range as a value (= range_to - range_from).
i've also modify the line-styles to make it look better.
the new version can be found here: https://github.com/pfsense/pfsense/pull/2054
