addd quick vhost support. simple wrapper macro coming soon...
fixing vhost bug in defroute (derr). adding with-vhost wrapp macro for setting up a set of defroutes to have a vhost. bitchin
vhost now matches on port (ut only if specified). if not specified, will match that host on any port. heh heh heh too easy
fixing bug: path was not url decoding when routing. fixed.
making with-vhost macro comment a bit more useful
integrated cl-fad in directory-router, hoping it would fix a weird bug in CCL where a filename with multiple periods has a > before the middle period(s). it didnt, but oh well its more portable, right?
larger internal (and external) changes to plugins

- you can now specify whether or not to load plugins via quicklisp
  (:use-quicklisp in load-plugins, defaults to T...get with the program
  hippies). if nil, loads via (asdf:oos 'asdf:load-op ...)
- :ignore-loading-errors in load-plugins now changes the loading
  behavior significantly. if T, loads each plugin individually as
  before, ignoring missing system errors and continuing to load other
  plugins where possible. if NIL, one system is auto-generated that has
  all the deps of the plugins we're loading listed in it and is loaded.
  this significantly improves plugin loading speed, and also behaves a
  lot more like asdf in general. works great.

so now calling load-plugins by default is extremely fast and works
great, assuming you have all the plugins you've enabled in your plugins
paths. otherwise, it'll bitch and throw errors (which is probably safer
anyway).
