[Fix #238] Boot support for ap

The syntax is identical and apparently `hd` also works (probably by
accident and we're modifying the real classpath instead of the intended
faux-classpath, but this seems better than nothing) so this fix was
trivial.

I can't think of any real issues involved in modifying the real
classpath, instead of the faux-classpath, in terms of the current repl
session, so until someone files a bug I'm not going to worry about this
difference between leiningen and boot.

 - Get rid of `cljr-reload-config`.  We're now sending the configuration options down to the middleware on each request instead of storing it down there.
 - Make magic requires cljc aware.
 - [#215](https://github.com/clojure-emacs/clj-refactor.el/issues/215) Improve the magic requires feature (when you hit `/`) by asking the middleware for all available namespace aliases.
