PROV-1038 Main record list exporter is now based on SearchResult and not on plain search expressions

This makes it easier to pass preprocessed sets of record, like ca_sets
or filtered+sorted SearchResult objects
PROV-1038 Added set based export option
NOJIRA Rename exporter manu item and remove export data option from exporter list

Data set exports will be available using either ca_sets or search tools
NOJIRA Fix minor annoyance

When updating an export mapping in one tab while editing an object in
another tab it could happen the the exporter list dropdown was
outdated, leading to a fatal error when trying to load an exporter with
that data. Not anymore.
PROV-1038 Moved exporter control to search tools
NOJIRA Add some additional access control to export
NOJIRA More access control
Merge branch 'develop' into authentication
