Build problems with using Go modules

[prologic]

I think this is some weird path problems when depending on your library using Go modules

See:

The hard-coded -I ./SDK/... in ultralight.go can't locate the include files.

To be honest I'm not really sure what to do about this besides forking/hacking your library for my own uses.

I managed to get pat the "file not found" issue by doing:

• Clone this repo outside of $GOPATH
• Ran go mod init github.com/raff/ultralight-go

And:

$ go run examples/resize.go
# github.com/raff/ultralight-go
./ultralight.go:318:32: not enough arguments in call to _Cfunc_ulCreateApp
	have (_Ctype_ULConfig)
	want (*_Ctype_struct_C_Settings, *_Ctype_struct_C_Config)

Looks like your bindings are slightly out-of-date?

Was able to get the examples/resizer.go working with this patch:
