Migration of Kallithea from Pylons to TurboGears2 completed

All, I am pleased to announce that the migration of Kallithea's backend framework has finally been completed. On the default branch, Kallithea is no longer using the deprecated Pylons framework, but TurboGears2 [1]. At the same time, the use of 'paster' has been replaced by 'gearbox'. If you are tracking the default branch and update to the latest version, do not forget to recreate your .ini file as there have been a few small changes. Also check the instructions in the manual, more specifically for using gearbox. There have been no database changes. At the next release, the release notes will obviously give more details. I would like to give a big thank you to Alessandro Molina (the maintainer of TurboGears2) for performing the bulk of the actual migration and helping us out with some of the problems we encountered during the cleanup and finalization. This migration wouldn't have been possible without him! I would also like to thank Mads Kiilerich for all the critical comments and suggestions he gave on the various iterations. While I admit it was tough at times ;-) this only helped in better understanding the actual changes, which in turn allowed splitting them up in bite-size changes that were easier to grasp and review, and organizing them in such a way that many preparatory commits could already be applied on top of Pylons-based Kallithea. Mads also performed the migration from 'paster' to 'gearbox' and helped with several other preparatory commits. Thanks! Thomas [1] http://turbogears.org/
