Updated several examples this morning to conform to new example template

Matt,

I have created several Pull requests this morning to update the following examples to more closely follow the current ARIA example template and fix the bug in menubar menu items for the space and enter key.


  1.  Menubar
  2.  Menu button
  3.  Checkbox
  4.  Radio button
  5.  Treeview
