Navigation

I fixed/added a few things:

1) Fixed alot of lines of code that lacked semi-colons at the end
2) Added navigation functions: moveTop, moveBottom, and moveTo
3) Changed quietPeriod Logic to not include the animation time. Some people will want to lock the scroll for less than the time of the animation. Does that make sense? I like being able to scroll faster/longer and be able to move 3 sections down, rather than have to wait for each sections animation to finish.

MoveUp and MoveDown could probably use the moveTo function now too... Also shouldn't it be movePrevious and moveNext? Doesnt really matter.

Good work on this plugin!!
