Finish MSBuild Task. about mb-unit HOT 8 CLOSED

I'm working on this now.

I created some integration tests that run msbuild and check that a correct exit 
code
is returned when 1) there are no tests, 2) the tests pass and 3) the tests fail.
I also created two new projects in the TestResources folders, one with tests 
that
fail and other with tests that pass (they are used to test the exit code).
I haven't uploaded the changes yet because I need to fix a few more things.

I committed a few changes yesterday. I implemented the reports-related and the 
filter
options and I uploaded some integrations tests.

I made the result summary to be logged as a Info if the execution succeeded and 
as
Error if it failed.

I created a bunch of unit tests, and found one or two bugs in the process. So 
now 1-4
are done, only 5 remains. I'm not sure how am I going to add new documentation 
since
that means to embed XML within XML.

You can write example docs with lots of embedded XML like this:

<example>
<code><![CDATA[
  <MbUnit Assemblies="..." />
]]></code>
</example>

However for the most part, clearly documenting the task parameters should be 
enough.
 Each should have a paragraph to explain what the parameter is for, what its
constraints, etc.  Maybe spend a bit of extra time on parameters like 
HintDirectories
and AppBaseDirectory because they're a little confusing.  The Filter parameter 
would
probably benefit from a few examples.

Done.
