Adding Build files, Fixed build related issues

There were relative path errors once the portal was deployed to a virtual
directory under IIS - these had to be fixed.

Issues such as css lookup paths.

Also fixed the summary page logout redirect issue by just changing path
template from /summary/{studentlogin} to
/summary?StudentLogin={studentlogin} - this is more of a hack since we no
longer have a RESTful looking url, but it should be fine for now.
