Build error due to dependency API change: multiple-value uuid.NewV4() in single-value context

[frankli714]

While building Jaqen, I got the errors:

offers.go:92: multiple-value uuid.NewV4() in single-value context
socket.go:93: multiple-value uuid.NewV4() in single-value context

This appears to be due to an API change in the dependency: https://github.com/satori/go.uuid
NewV4() now returns an additional error value, changed in commit satori/go.uuid@0ef6afb

Build works when you change those two lines to accept a second value, for example: id, _ := uuid.NewV4()
