[CMS] Marker popup should show the right content from the Point/Place model

[rudokemper]

Currently, the marker popups show the following content:

[title] (in the popup header)
[region]

It should be the following:

[title] (in the popup header)
[photo]

Region: [region]
Type of place: [type_of_place]

[description]

For region and type of place, if there is no content, then the label does not need to show.

NOTE: this issue is depending on issue 162 being resolved, because some of these data fields still need to be added to the Point/Place model.
