[development] let's cleanup /misc

> Opsie, what I suggested is multisite.
Don't forget that multisite, while good could be a pain for upgrades.
The code upgrade is easy, but the database upgrades of a bunch of sites
are a pain. 

At the moment we don't have an upgrade approach for that, just a set of
floating rumors how to do it easily, so that we minimise downtime.

The various softlink farms, etc... 

When suggesting and deciding on a change we need to consider such
approaches, so that drupal is easily 'farmable'. Hosting providers
will love us for that.
