Cannot use steamworks4j-lwjgl3 in gradle projects

[Rizato]

Doing a gradle sync with the steamworks4j-lwjgl3:1.10.0-SNAPSHOT results in an error of Could not find lwjgl-3.3.1-${lwjgl.natives}.jar (org.lwjgl:lwjgl:3.3.1).

Gradle has limited support for Maven profiles.

See gradle/gradle#20164

Right now neither the libgdx, nor lwjgl3 loaders work on macos with gradle projects. See #117, which also affects intel macs.

Restoring the SteamAPI.loadLibraries() function is probably the easiest/fastest path to working on macs again.
