- No random chdir() calls
- No more exceptions when executing scripts from dirs other than root
- find-posts.php prints absolute paths making piping more useful
- Most of model-related code moved from controllers to model classes, much
fewer calls to R::whatever() in controllers
- Post editing and uploading shares the same code, thus making implementing
stuff easier in the future
- Added support for default bean wiring, no more calls to R::preload() all over
the place
- More robust concurrent post editing detection
