Updated projects model to reflect a user demo.  User demo will need to be an mp3 and validations will come next!
Added demo validations and also fixed projects/new render page to be more in line with previous styling.
Added additional styling, also helped form elements be more in line.
Fixed view to be more complacent with user upload structure.
Added tags through a polymorphic association tag-> taggings <- projects.
Fixed carrierwave issue regarding user demos
Added validations & testing for tags, tagging & projects
Fixed search functionality to include title & description (not case sensitive)
Also fixed view to of index to correctly display search results vs main index page
Merge pull request #4 from allcentury/projects2
