  19  * We only want to use steamworks if building for the networked version,

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