introducing page templates - need to add edit capabilities

renamed the custom template folder

forgot one fix for the new custom template path

page templates refined

renamed page attribute template to template_name as i suspected it to be a reserved word. it still didn't work until i discovered that simon defined the accessible attributes! That costed me 40 minutes of lifetime. But he apologized ;)

tests for public and custom page templates
