jp (blog): edit command, first draft: - can edit a new or existing item, by default edit a new item - item are selected with a shortcut, for now only "new" and "last" are handled. URI handling is planed, specially xmpp: URIs - file are edited using EDITOR env variable, or editor in [jp] section in sat.conf - current syntax is used, file extension is choosed according to syntax, to make syntax coloration and other goodies in editor available - if file is empty or not modified, nothing is published - for now, title, tags and commend desactivation are handled with optional arguments, but other are planed, and a metadata system should come soon
