Add fast-mode Uri class.

Browse source 
Optimize parser and make it recognize a class of URIs that don't need extra
handling: no escapes, no funny characters, already (nearly or completely)
normalized.
Have a class specifically for those URIs which retains the original
input string without having allocate any further strings.
