Tablix 0.2.2 development release

Third development release of the 0.2.x branch is available for download

This release fixes a few critical bugs in the kernel and adds a lot of fitness modules (most of them contributed by Nicholas Robinson). A new automatic module documentation system has been added and I've updated and extended the first part of the Modules HOW-TO. No API changes have been made and modules written for the 0.2.1 release will work with 0.2.2 without modifications.

A lot of modules haven't been ported to the new kernel yet, however this is the first release of the 0.2.x branch that can be used to solve real-life problems. On the other hand a lot of things still need to be done before the first stable release of this branch. Any help is appreciated.
