Bug Fix and Cleanup of Install.edify
* Photosphere Force Changes
    1. If you forced to install and previously forced NOT to install, the "no" file would be prefered over the "force" file causing it to not be installed.
    2. If you said no to both but have previously forced yes or no, it would "force" or use "no" photosphere files that already exist.
   The solution was to have each step delete the files not in use.
* Added Headers to each section of the file.
