Sync Humble Sept 25 (#637)

* Optional map saver (#633)

* Add parameter to stop map saver from being initialised

Map saver will subscribe to the map topic and force updates of the map
even when nothing else is subscribed.
This allows it to be turned off to save processing cycles.

* Add details of use_map_saver parameter to README

* Add defaulted-true use_map_saver parameter to launch configs

* adding namespace support for map saving (#613)

* fix mismatched service name in rviz plugin (#634)

* bumping to 2.6.6 for release
