Wiki: module exchange

[Paul A. Rubin]

I noticed a hint in one of the messages here that led me to discover a 
user-supplied module on the wiki: http://wiki.lyx.org/Tips/Enumitem.  I 
had to do a search to find it, though.

We have a page on the wiki for sharing layouts and tips about layouts. 
It might be a good idea to start a similar page for exchanging modules 
and tips about them.  Sadly, I have negative idle time (but positive 
stress) at the moment, so I can't follow up on my own suggestion.
