mod_storage_sql: Record connection to database as module status Allows retrieving this in e.g. a health reporting module Thanks pfak

mod_admin_shell: Match substring in muc:affiliations() like muc:occupants() Maybe one day we'll get consistent filtering semantics everywhere.

mod_admin_shell: Sort MUC users by relation and JID Suggested by MattJ, our resident UI expert :)

mod_admin_shell: Make Role and Affiliation columns the same width for aesthetics The length of the title "Affiliation" made them both close enough that it looked off.

mod_admin_shell: Use tables to present MUC users Tables are awesome!

mod_admin_shell: Factor out room retrieval into common function Justification: See diffstat

mod_admin_shell: Add muc:affiliations(room) command to list memberships Easier than going trough muc:room():each_affiliation() since you have to do fiddly things to reach the print() function.

mod_admin_shell: Add muc:occupants(room) command to list occupants Easier than going trough muc:room():each_occupant() since you have to do fiddly things to reach the print() function.

util.startup: Close state on exit to ensure GC finalizers are called Ensures a last round of garbage collection and that finalizers are called. Fixes things like proper closing of SQLite3 state. There are more calls to os.exit() but most of them exit with an error or in a case where a final GC sweep might not matter as much. It would be nice if this was the default. Calling util.statup.exit() everywhere may be sensible, but would be more involved, requiring imports everywhere.
