  17  * We only want to use steamworks if building for the networked version,
  18  * theres not much point otherwise. We mainly want steamworks for setting
  19  * achievements etc.. so that includes our own server too.
  20  *
  21  * This file also wraps the functions and interfaces that we want to use to
  22  * make them a bit easier to read, since they are the flat API they have very
  23  * long names. in non-networked builds they will return default errors or do
  24  * nothing.
