Get rid of static caching of created arrays. These have to be rebuilt if a different language is needed. Extended the default Intl Collator class with a ksort() method.

Changed sex to comply with ISO 5218.
Removed placeholder avatar images. Avatars have to be uploaded via the provided form.
Disabled opcode cache completely for development.
Correcting some minor issues in the install script. They are all a mess and we definitely have to create packages for easy install and uninstall.
Images are stored in the database, therefor we have to integrate this in the Models. The user model is pretty easy, because it only has a single image.
Updated everything to reflect latest changes in image handling, sex change, and much more.
Updated README for the user directory.
