NEW UNICON - Part I

Began the basics of a new UniCon (object spawning system).

new command: "/create"

example /create box name,info,stuff,actions

creates a Glass with fields medotype: "box" filled and disabled and
empty fields: name,info,stuff

new function UniCon in chatbox.js catches and parses the command.

Currently catches "actions" as a preset model object attribute. To code
into MEGlass.js a new method for filling a Glass panel with an "action
checklist" that will read from a system crystal the available actions.

some fixes to some models, some new computed properties.

old items in the DB may break as a result of this patch.
