Add marine/freshwater/terrestrial status to occurrence record

[sophiathirza]

At the moment the marine/freshwater/terrestrial status for a taxa is only on the species search in the habitat term. Please could it be added to the occurrence records as well.

• The value should come from the species, i.e. it will not be supplied with the data
• It should be possible to search/filter for occurrence records by habitat.
• Habitat should be included on the occurrence record page
• Less important - habitat could be included in the occurrence record downloads

Could be done at the same time as #582.

Habitat is a single value field on the species component. Ideally it should be changed to multi-value to make searching easier.
