Code review fixes
Created a view for a slider that cycles through top donors. Several images had to be cropped for this. The JS file has to be externally loaded because this will go in pages written in .md rather than HAML.
Changed name and location of thumbnail files.
Added a helper method to retrieve the thumbnail image for a donor based on name.
Created HTML elements using a loop and database query rather than hardcoding.
Made JS behavior more abstract to accommodate any number of donors properly.
