User impersonation

####User impersonation

As of Redmine 2.2.0 you can impersonate user setting user login (eg. jsmith). This only works when using the API with an administrator account, this header will be ignored when using the API with a regular user account.

Example:

var host = "<host>";
var apiKey = "<api-key>";
var login = "<user-login-to-impersonate>";

RedmineManager manager = new RedmineManager (host, apiKey);
manager.ImpersonateUser = login;
