 * PluginManager manages plugins.
 * There are two plugin types: binary and scripted.
 * Binary plugins are dynamically loaded shared libraries (dll/so) which
 * can do pretty much anything with the SDK.
 * Script plugins are more lightweight and are very convenient for
 * smaller scale/functionality plugins.
