[cgiapp] Incompatibility between CAP::Authentication and CAP::ActionDispatch

[Nicholas Bamber]

I've uploaded 0.17_5 which has the ActionDispatch fix and hopefully 
should run fine without ActionDispatch being installed.

The question Christian raises about Dispatch is interesting. As 
Christian points out I am not a fan of setting up run modes by setting 
subroutine attributes. I can see that it makes the code look nice but I 
do not see what the practical benefits are.
