#3 Changes to MockDynamoHttpServletRequest

[Piran Montford]

Two changes to
com.mockobjects.atg.MockDynamoHttpServletRequest:

1. Fix a bug in getLocalParameter. The method is
currently casting to String before returning. The
method should be able to return any object -- the
return type is Object.

2. Change in serviceLocalParameter. If there is a
local parameter, then try and service it, i.e. call
its service method. This requires the fix in bug 1,
and can be used with MockDynamoServlet submitted in
another bug.

Plus: imports and a couple of changes to whitespace.
