[#20583] Snap Cursor to Center and more View edits

Patches by Jonathan Smith (jaydez) 

Add a Cursor Center entry in the snap menu (Shift-S) to reset the cursor to 0,0,0. Also rename the view_center operator to view_selected to reflect better what it does (in the code only, description and name were already ok).
