add GetCurParAttr and GetPaMParAttr in SwEditShell

GetCurParAttr : Get the paragraph format attribute(s) of the current selection.
GetPaMParAttr : Get the paragraph format attribute(s) of the selection(s) described by a SwPaM.

The advantage of these methods is that the take the named and automatic
format attributes.
