Let's really release 2.4.0 soon

[Christian Stimming]

The subject says it all: We don't have any further bug with milestone 2.4.0 
open, with the exception of 4 documentation issues:

https://bugzilla.gnome.org/buglist.cgi?product=GnuCash&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&target_milestone=2.4.0

However, (almost) nothing happened on the documentation parts for the last 3 
weeks. I suspect it is going to stay this way for the weeks to come. Hence, if 
we don't want to delay the 2.4.0 release of the *program* forever, we must 
admit we won't have the documentation completely up to date but nevertheless 
we release the program because it is stable enough.

Hence, I propose to release 2.4.0 ASAP, e.g., this weekend: December 18th.

The next documentation and translation updates can follow in early January. 
But if we don't step ahead with 2.4.0 *now*, we won't see it before January 
due to the Christmas / Holiday break. Please please go ahead and release it 
now.

What do you think?

Regards,

Christian
