doc, json, ipc, and settings

All in the hs.<mod> name space, but I figure not an issue for these... they're pretty much expected. To install the command line tool, hs, do this from the console:  `require("hs.ipc").cli_install("/base/path")` ... if you leave out the argument, it installs to /usr/local.  hs.doc.doc_for_file is just waiting for whatever json file you end up creating.
