-First cut of the House ("deal". "house". Geddit?) server. Nothing functional yet, just laying the groundwork based on my prototyping
-Broke the sym->keyword utility function down to ->keyword and made it a method (currently defined for symbols and strings)
-Added direct dependencies to house.asd
-Light renaming in house.lisp
-Added most of the write! mehtod definition
-Added package imports to house (aif and awhen from the deal project)
Still todo:
      Handler definition macros and auto-session setup
-Baby steps towards a handler definition mini-language
-Working session auto-assignment. Next up:
	 - Put together the stream handler
	 - Put together the new define-handler mini-language
-Removed diagnostic logging message
-handlers and stream handlers are now separate (it's up to the handler to clean up its connection; you should do the unwind-protect thing)
