aliased imports so that Hashtable usages are changed to OrderedDictionary

The binaries produced by cecil are non-deterministic due to the use of
unordered collections (eg System.Collections.Hashtable) in Cecil.

I propose changing them to System.Collections.Specialized.OrderedDictionary.

The current usages are primarily for small collections (eg annotations), so
there shouldn't be a noticable performance hit.

I took a shortcut and changed the usages via aliases imports.  The change to
the mono codebase should probably not do it this way.  Anyway, patch attached.
