  22  * achievements etc.. so that includes our own server too.
  23  *
  24  * This file also wraps the functions and interfaces that we want to use to
  25  * make them a bit easier to read, since they are the flat API they have very
  26  * long names. in non-networked builds they will return default errors or do
  27  * nothing.
