Table-responsive should have overflow-x: auto;

Created by: nadangergeo

Table-responsive should have overflow-x: auto; instead of scroll so that the scrollbar won't be visible unless the div is overflown.

When overflow-x is scroll, Chrome (v35.0.1916.114 OS X 10.9.2) show the scrollbar even if the div is not overflown. Safari does not do this. The change is needed for consistency.
