Disable / Enable ScriptingDefineSymbolds from menu

ScriptingDefineSymbolToggler.cs

/*  To avoid performance issues caused by string constructions when logging stuff
 *  to the console, simply surround the code with the the following:
 *  
 *  #if DEBUG_LOGGING
 *  Debug.Log("my" + numer.ToString("0.00") " super" + " expensive " + " string building code");
 *  #endif
 *
 *  When creating a non-debug build or testing the game for performance, simply disable 
 *  the debug messages from the Unity menu (menu name can be simply changed below).
