start webserver automatically - Fixes #9

Note that this will only take effect on new installations of JMR-Pi
as by default JMR-Pi will not overwrite exising PanelPro Configs.

If you want to enable this manually, add the following line toward the
bottom of PanelProConfig2.xml:

  <perform name="jmri.web.server.WebServerAction" type="Action" class="apps.configurexml.PerformActionModelXml" />
Merge branch 'master' of github.com:proffalken/JMR-Pi
