Auto-wrap selector in necessary HTML nodes, smooth scrolling & iOS FULL support

[kakysha]

1)added tinyscroll() method that auto wraps selector in necessary divs and initializes scrollbar's sizes.

2)added 'duration' parameter to tinyscrollbar_update() function which scrolls smoothly to a certain destination.

3)added FULL iOS support. I mean, from now on you can scroll directly by 'swiping' the content with one finger, not only by scrollbars.

Sorry for total file rewriting, but i was working on 1.66 version of your library downloaded from your site. Dont know why there is the older version of library (1.65) on github.

Hi there, I'm not the original author, I just put it up on github for my own purposes. If you'd like to help maintain the library, feel free to do so on your own fork.
