Fix to work with http chef_omnibus_url

Often people will reference getchef.com with http rather then https
for either using proxy caching software or due to The Enterprise
SSL proxy.  This allows the chef_omnibus_url to properly be updated
from .sh to .msi when referenced with http and not https.

This also includes some styling fixes that Sublime Text automatically corrected (end of line space removal mainly).
