3. A warning is generate if a DIR in the appBase is ignored because
there is a matching WAR and unpackWARs==false.

4. Adding an XML or WAR when just a DIR exists will trigger a redeploy.
If a WAR is added and unpackWARs==true, the DIR will be replaced.

5. If a WAR or DIR is added to an XML, a reload will occur and the
failed context will start serving content provided by the WAR/DIR.

I believe that the test cases are complete.

I plan to let this bed in for a while before back-porting the HostConfig
and ContextConfig changes to 7.0.x.
