* @brief A convenience class for loading templates using .kdevtemplate files

* The locations for loading and storing files are determined by the typePrefix.
* We use KStandardDirs with the "data" type and create a filter string as such:
* \li templates: typePrefix "/templates/"
* \li descriptions: typePrefix "/template_descriptions/"
* \li previews: typePrefix "/template_previews/"
