Port to D8

patch doesn't apply against sms_simplegateway-7.x-1.x-dev.tar.gz, here is the error.

sorry my fold, I had some problem to apply the patch, I just applied succesfully. I'll test asap.

ciao almaudoh,
when I try to register the mobile number I get this error.

sorry again, it seems the patch wasn't properly applied. I patched manually the module files and now I successfully registered mobile phone number. I'm now ready to test the port.

pls commit the patch and create a 8.x branch. thanks.
