Tweaking inn.conf values for INN 2.6.0

At the same time, I also suggest changing the default of use-mmap in 
innfeed.conf.  It is currently set to false; it specifies whether 
mmaping should be used.  The caveat in the doc is that "if article data 
on disk is not in NNTP-ready format (CR/LF at the end of each line), 
then after mmaping, the article is read into memory and fixed up, so 
mmaping has no positive effect (and possibly some negative effect 
depending on your system), and so in such a case this value should be 
false".

In current modern systems, I suppose it no longer has negative effects.


max-queue-size could also be increased in innfeed.conf.  Its default 
value is 5.  It defines the maximum number of articles to process at one 
time when using streaming to transmit to a peer.
With current amount of available RAM, we could perhaps increase it to 20 
by default.
