closes #9

Added support to edit own pages using ckeditor. now you should be able modify front_page in easy way.
Also you are able add own help pages etc.
Right now access to add/edit is set only for Administrator role.
As this feature is in experimental phase you need to enable it by adding
config['pageeditor'] = true;
After "git pull" you might need to run doctrine-cl to regenerate proxies

to create own default public front page you need to set front_page as article id in the form.
