Fixed a memleak in libedit undo buffer, minor code cleanup 

In LIB_EDIT_FRAME::GetComponentFrom{Undo,Redo}List() methods, the
PICKED_ITEMS_LIST object which was retrieved from undo/redo list has not
been destroyed.

Rewritten SCH_SCREEN::ClearUndoORRedoList() to be easier to read.

Minor whitespace formatting.
