refactors the query string search plugin + pagination

• The RestoSearch plugin is dismissed and merged with its parent to allow
  better generalization of the QueryStringSearch plugin.
• A mecanism that enables walking through all the search results of a
  provider is also added (see Add pagination to the search interface #58).
• An enhancement on how the free text search configuration parameter is
  resolved is also introduced (it may be of interest to make this
  mechanism the default way of handling search parameters to enable
  searching by an arbitrary number of metadata)
