Good idea of being able to enable or disable pagination of projects
list.  

I am not sure though if this is the correct solution.  First,
pagination in all other places is hardcoded to 100 items per page;
IMHO for consistency it would be good to use the same page size
everywhere.

Second, perhaps instead of yet another global variable a better
solution would be non-verridable %feature, like 'pathinfo' or 'forks'
features?

Hmmm...

In other places we have 'first' &sdot; 'prev' &sdot; 'next'...

... is there a reason to not use format_paging_nav() subroutine?
