fixed example with relative path
had some trouble getting the example to load a relative path because all path references the program was receiving was from the love.exe and not the directory with all the code. had to use the input arguments to the love.exe to get the game path. also, all the love filesystem functions are relative to either the love.exe or the game code, so i could not check the inputs of the love.exe to see if one was a folder because it wouldn't take an absolute path ... anyway, it works now and should work for all examples as long as the main file is copied and used as a base.
