AI 144940: ADT #1722971: Fix refactoring menu contribution for Eclipse 3.3/3.4 on Linux/Mac.

The fix is that a menu contribution should redefine the menu that it is
  contributing too. In this case it seems the JDT is not yet loaded or at
  least hasn't defined the menu that we're contributing too, so we need to
  define it. This definition is extracted from the jdt.ui/plugin.xml from
  3.4 in order to define the same group names in the same order.
