	<rdar://problem/3685235> REGRESSION (Mail): links are not properly editable

	* khtml/html/html_inlineimpl.cpp:

	the normal focus rules so the link does not swallow focus when you arrow key
	or drag-select into it.

        * WebView.subproj/WebDefaultUIDelegate.m: By default, don't allow
	link dragging if the element under the mouse pointer is
	editable. This way, you can drag-select starting inside a link.
