FR: scroll such that it is on tab boundaries

[gregveres]

It would be nice if there was a mode where scrolling was only done on tab boundaries. Ie, if I page to the right, then the tab that is shown first in the list should be completely visible. This would help a lot with the aesthetics of the control as people are interacting with it.

I went ahead and implemented this. It can be found @ gregveres/bootstrap-nav-tab-scrollable (forked from here).
I don't expect that you will want to do a pull request because I didn't change this to be an option, I just implemented it so that it worked this way rather than landing on partial tabs.
You may want to look at the code though. I did a few things that you may want to bring into your code:
There was at least one place where you used width() instead of outerWidth().
I capture all the jQuery selectors into variables so that I am not doing the jQuery finds all over the place - especially during the manual scroll and resize event handlers.
I added a debounce (shamelessly taken from: jmosbech/StickyTableHeaders) to the scroll and resize handlers.

Anyway, thanks for creating this in the first place. This version works really well for my purposes.
