Validates whether an image is acceptable through mime type

image/jpeg, image/png & image/gif are considered the allowed mime types
for an image. mimemagic gem is added as dependency in order to do the
checking.

Added tests to check against three supported mime types. A fake jpg
fixture (created with 'touch' command) has been added to test that
extension is no longer used.
