Fix #84: add server info to /version command.

This command now queries the server for a version string
according to XEP-0092, and prints it if the server returns one.

(Not all servers support this, in which case there is no output.)

Fix #91: Save settings after deleting alias.

That was an easy one.
Fix #89, fix #73 for real; /list empty check.

JS objects don't have a length property. Instead of checking for that,
this patch just checks the links array we generate.
Fix #90: Do not suppress 'duplicate' messages.

Since the history is now cut off automatically, any duplicate
messages are supposed to be there.
Fix #87: set textColor default to '', not null.

objMerge will otherwise discard values by type mismatch.
