The jlib:rsm_decode/1 function sets the 'max' and/or 'index' elements of
the returned 'rsm_in' record to 'error' if the parsed strings cannot be
converted to integer values.

ejabberdctl: Escape whitespace in ERL_OPTIONS

If ERL_OPTIONS="-opt arg" is specified, make sure the space character
between "-opt" and "arg" is retained.

Fixes #143.

This allows to remove any argument to joincluster/leavecluster scripts
when no parameters has been added after the ctl command.

If ERL_OPTIONS="-opt arg" is specified, make sure the space character
between "-opt" and "arg" is retained.

Fixes #143.

(Thanks to Christophe Romain.)

This is a preliminary version that is tested to work with the packaging
branch of ejabberd-modules repository

This version lacks automatic configuration include at runtime

As per version 1.25 of XEP-0045, use the room JID as the 'from' address
for <delay/> elements also when the room is non-anonymous, and specify
the original JID of the sender as an XEP-0033-style tag instead.

Closes #465.
