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