Reduce ambiguity in output format

[tfalamu]

Currently, the output looks something like this:

$ httpcode 404
Not Found

This could be misleading as the user is unsure if the code is "Not Found in the corpus" or the code represents "Not Found". A better output format should eliminate all ambiguities. An example would be:

$ httpcode 404
404 means *Not Found* 

Or something more fancy, maybe.
