Added SBT-Revolver

Added the plugin and the settings to the Build file.
Seems to be working decently. woot woot.
Updated ConfigLoader to be less noisy

Just moving the logging of every time the routes file is
being re-loaded. Myabe we'll add it back later if anyone finds
it useful.
Added Route Matching

Doing a lookup based on path and responding with a no-body 404 with
a custom X-Not-Found-Reason that specifies that a route could not be
found.
