Better merge of CloudLab landing page and CloudLab portal
The CloudLab landing page and portal are currently two different codebases merged by an ugly set of apache directives. The directives say to first look in the landing page location for a file and if it doesn't exist look in the portal location. This is ugly now and will likely cause confusion later. I am refactoring the cloudlab landing page to remove the need for these directives. Instead, there will be a small set of concrete directives for a small number of particular locations in the landing page location and everything else will come from the portal location.
