Respect overflow-x and overflow-y settings to prevent scrolling in a given plane regardless of content

[vitch]

On native overflowed elements it is possible to set either or both of overflow-x and overflow-y to hidden. This should also be allowed in jScrollPane as a way to restrict scrolling to a given plane even if the content is wide/ tall enough to trigger scrolling in the other plane...

I agree with this, as:

overflow-y: scroll !important; overflow-x: auto !important;

works perfectly without jScrollpane, but jScrollpane ignores this and scrolls both directions.
