Display suggestion is now configurable.

Commit 665772bda213e838b3c092075a386ee3b846b0be forces to display only
suggestion for the request's method (this was not the case before).

This commit allows to configure this behaviour: it keeps the current behaviour
but also allows to use the other behaviour where the suggestion is displayed
for each request method (as it was before).

Use port number 9090 instead of 80

Port 80 is often already used by standard webservers (Apache, nginx, ...).
Moreover, on Linux, ports below 1024 can only be opened by root.

Socket: reuse address to resolve the error "address already in use"

On Unix, when we stop the server, and then re-start it right away, we get an
error that the address is already in use:
http://www.softlab.ntua.gr/facilities/documentation/unix/unix-socket-faq/unix-socket-faq-4.html#ss4.1
This means that the sockets that were used by the first incarnation of the
server are still active.

One way to resolve this is to set the socket option SO_REUSEADDR:
http://www.softlab.ntua.gr/facilities/documentation/unix/unix-socket-faq/unix-socket-faq-4.html#ss4.5

Tested on Ubuntu 12.04 LTS
