Feature: upper case route if route is non-numeric

[blakeyoder]

What are your thoughts on having the route be upper cased for all non-numeric routes.

/by-route/G and /by-route/g would return the same data set. As is, the lower cased route returns an empty list.

I like that suggestion - returning an empty list is a pretty confusing response. What do you think of canonicalizing on either upper or lower case, and having the other case return 301 redirects to the canonical URL?
