New "Introduction" section with renewed "Contributor's Handbook"

Have a look at the newly introduced “Introduction” section added to the top menu of the site.

In it you’ll find the existing introduction page as well as the recently introduced “Website Manual” which have gone undetected by many of you when it was subtly added to the “Home” section a couple weeks back.

Most important is the brand new “Contributor’s Handbook”. This is a WIP rework of several related wiki pages. One of the most significant changes yet to come is that all of the “Priority Projects” listed so far will be replaced by a unique jobs listings theme as soon as we get the help needed to enable multisite. I’ll elaborate on the jobs board as soon as we have more definite plans.

Please browse through the new contributor’s handbook and let me know what you think.
