portletUnit

portletUnit does not seem to handle encoded parameters correctly.
If one uses HttpUnit to build a request, httpunit encodes the parameters
automatically. For example "foo bar" becomes "foo+bar".

When you use PortletReuqest.getParameter(..) in your portlet you get
"foo+bar" instead of the expected "foo bar" value.

The API says that the parameter should NOT be encoded

tParameter(java.lang.String)

Not sure where the fix should be applied. PortletUnitPortletRequest.java
would seem to be the most obvious place, but perhaps there is a better
location.
