Fixes #5562, #6024.  Re-evaluation of IE's CSS expressions was causing a slow down.  Occasionally the expressions would throw an error causing the "Invalid argument". Removed IE font-style and font-weight inheritance from input tags used in dijit widgets to prevent css expression re-evaluation.  Font-family and font-size are still inherited by child input nodes as before, but if the parent node's font-family changes (unlikely), the child input node will not pick up the change.  This prevents constant css expression re-evaluation.  All font attributes can still be specified for the input node if the IE defaults are not acceptable.
