First implementation of score multiplier..

Currently it is in the player and it affects the score gained from each ScoreBall.
It has to be placed into ScoreBar so it affects the speed the bar increases.
Fixed bug when reloading a level..

Spawner now empties and unloads the graveyard when it is reset. Active will be reset by Screen
Improved spawning algorithm..

Friendly and enemy circles now have their own portal spawning index.
AddBall doesn't need a portal parameter anymore.
AddBall gets a portal depending on spawning an enemy or friendly.
Changes to score algorithm..

Multiplier now completely in ScoreBar.
Score now from 0 to 100 instead of a value given by level.
Changes made mostly in ScoreBar and PlayerBall to adept to the new Score system.
