#14 Additional methods in MockStrutsTestCase

[Jason Edwards]

The patch adds the following methods to MockStrutsTestCase:

getRequestURI()
setRequestURI()
getResponseLocationHeader()
setResponseLocationHeader()

I am using Stxx (http://stxx.sf.net), and the
HttpServletRequestSimulator::requestURI was not being
set. Additionally, the "Location" header was not being
added to HttpServletResponseSimulator::headers. I
don't know if the problem is in Stxx, or if it's
something I'm not doing properly, but I think these are
two useful methods.

Adds get/setRequestURI() & get/setRequestLocationHeader() to MockStrutsTestCase.java
