Adding a manual User-Agent get overwritten by the User-Agent of the RestClient #787
Description
When adding a header like this
restClient.AddHeader("User-Agent","My-User-Agent")
the RestClient will overrule this with the default "RestSharp 1.x.x.x" like is discussed in this issue. Can this be fixed, so that in the future, people will not be weirded out, when they need to set the User-Agent and it doesn't do anything? ;)
