URL encoding the user/pass for dnsomatic, since it accepts all characters.

I made a modification so that all characters could be used in the user/pass fields for DNS-O-Matic.  It may be something that can be expanded to other dynamic DNS services that support all characters.

"To remove a curl_setopt line that is unused for "dnsomatic", and to allow for all characters to be used in the username and password fields."
