Title: Map saver update

Minor changes enabling me to create maps (images) from global costmaps.

Changes

* costs (probailities) between lethal objects and free space are considered to be free space (in our use case these costs came from the object inflation)
* unknown space is converted into grey areas

@AlexReimann please review
