Add sorting and limit to default links widget

[yoavf]

The default links widget is kinda dull, and to tell truth - he's really jealous of his brothers recent post and pages widgets.

So here's a little patch to add sorting order and limit to the widget.

+1 - I've heard a lot of requests for this.

Sorry to have to be a pain, But since this isn't a regression, is an enhancement over what we've currently got & we're in a feature freeze, I'm going to bump this to early 3.1.

Let's get Jane to weigh in on this before proceeding.

Refreshed patch for trunk.

Freeze has arrived. @rboren: I hear this has been running on .com for a while. Any issues? If you want to commit, its fine with me.

Replying to yoavf:

Refreshed patch for trunk.

WP_Widget_Links::widget() contains

$order = isset($instance['order']) ? $instance['order'] : 'ASC';

but order is not an option in the form and is never set on update.

I think that either the user should be allowed to choose the ordering via the form, or:

$order = 'rating' == $orderby ? 'DESC' : 'ASC';

Punting enhancements from 3.3.
