Title: #88 dhcpcd: Add option to prevent dhcpcd from clobbering /etc/resolv.con...

...f

Without this option enabled dhcpcd will insist on overwriting
/etc/resolv.conf even if has been modified manually, or by using a
program such as wicd.

After enabling this option I can restart dhcpcd and /etc/resolv.conf remains intact.
