Also handle Route templates

Following measures:

* Split up into two classes
  * TemplateDialog: the general dialog
  * TemplateManager: A widget to rename and remove templates

* Make TemplateManager abstract and derive a class for session templates and
  one for route templates. This is needed, as session templates and route
  templates are stored in a different way. Thus we need different methods to
  rename and remove them.
