Guide system simplified

Short announcement to all guide writers, the following change has been made:

Drafts no longer exists. They have been replaced by "Work in Progress".

That means that when your guide has the status of "Work in Progress", only you and the admins can see it.

Once you change the status of your guide to "Finished", it finally becomes published and everyone can see it.

This is to encourage people to publish guides in a more polished state, because sadly, we get a lot of guides on the front page which could barely be called drafts, and I want to change that.

We want a higher level of quality for guides and that's the first step in this direction.
