added new function to carrierwave to increase quality of uploaded photo

Fixes #79 
When I load a picture into an art piece then visit the index page for the
art pieces, that displays a thumb of the picture. When you look at the
pictures in the carousel, they are not very big, yet very clear now, When
you click on a picture and light box it, its a small amount larger than in
the carousel but way more clear.
