Add Project.centroid and fix project maps fixture
Strip parts after centroid split
Fix project maps group by clause to none

New Project map is not grouped. It shows a marker
for every project with centroid
Change Project select clause
Implement new Project api backend.

This commit keeps previous implementation for
debugging purposes and more manual checking.

All select, from, where, grow by, having and filters
were moved to maps.views so they can be shared with
others views like investment and organization.

This new view has a better test that checks actual
json output value to search for specific data.
Use new api and fix info box information
