October 2011: changing core wiki engine from PmWiki to Concrete5!

And changing architecture from 32 to 64 bits, new location in UK (before: US west coast), new webserver (Nginx instead of Apache).

A lot of stuff still outstanding, so please be patient if the site goes offline from time to time or if things are not working as expected.

Edit 31.Oct.2011: went back from Nginx to Apache - Apache is just more "standard" than Nginx and some of the functionalities (e.g. Digest passwords) are not available in Nginx or I did not understand how to use it.
