//When doing an debug build just load the mod lib from the basepath as that will have the debug pointers

// Now the code always just unpacks new libraries from the packs on release builds.
// So the libraryfiles in the homepath are always refreshed with latest from the packs.
// This fixes many issues with clients loading old libraries from the mod paths.
//
// The way it used to work is described under (or in debug mode)..
//
// if the server is pure, extract the dlls from the mod_bin.pk3 so
// that they can be referenced
//
// If the server is not pure, then the
// lib must either already be in the homepath, or in the basepath,
// without being in a pak. For a pure server, it always grabs the lib
// from within a pak. This means there must be two copies of the lib!
//
// So now, if connecting to an impure server, and the lib was not
// loaded from homepath or the basepath, let's pull it out of the pak.
// This means we only *need* the copy that's in the pak, and will use
// it if another copy isn't found first.
