random integer and seeded random generator

See if you like it, test with:

    // 10 random floats
    for ( var i = 0; i < 10; i++ ) {
    	console.log( game.Math.random(1, 10) );
    }
    
    // 10 random integers
    for ( var i = 0; i < 10; i++ ) {
    	console.log( game.Math.randomInt(1, 10) );
    }
    
    // 10 random seeded floats (they are always the same per seed)
    game.Math.randomSeed(1);	// seed the random number generator (defaulted to Date.now())
    for ( var i = 0; i < 10; i++ ) {
    	console.log( game.Math.random(1, 10, true) );
    }

    // 10 random seeded integers (no need to reseed the generator)
    for ( var i = 0; i < 10; i++ ) {
    	console.log( game.Math.randomInt(1, 10, true) );
    }
