Adding the ability to control looping

[davidgeere]

I like the simplicity of this library. I do though think it could use the ability for a developer to set if it never loops, always loops or loops n times. So I added some code that if you add the attribute as such:

• It will loop for ever (it's also the default) data-loop="true"

• It will not loop at all, it will just type out once. data-loop="false"

• It will loop 4 times data-loop="4"

This unfortunately only works with non-delimited words, mainly because multiple delimitations was just not a use case for me. I will submit another change once I get to that.

Thank you for making this improvement, I love it! I had just one comment before I want to pull the change.

Thanks for updating-- since true == 1, this.loop <= p.looped was activating if dataset-loop was not set. Since string < number is not true, the new version is fine.

Awesome, thanks Steven! Thanks for creating this library in the first place. :)
