Enable http sessions with unfiltered-jetty

[sadr0b0t]

https://github.com/unfiltered/unfiltered/blob/0.8.4/jetty/src/main/scala/contexts.scala#L25-L29
changed single line in contexts.scala:

   val ctx = new ServletContextHandler(parent, path, false, false)

to

   val ctx = new ServletContextHandler(parent, path, true, false)

This sets ServletContextHandler constructor parameter sessions to true

http://download.eclipse.org/jetty/stable-9/apidocs/org/eclipse/jetty/servlet/ServletContextHandler.html

ServletContextHandler(HandlerContainer parent, String contextPath, boolean sessions, boolean security)

Now I have sessions working with jetty like:

println("session id:" + req.underlying.getSession.getId)

session id:1v6stys8pjmdqfjm3vxtzfohr

Session id is required for example for form-based authentication.
