#1 Add a openstreetmap export tool

[James Michael DuPont]

the tool should be able to export the data in openstreetmap format.
it uses the generic autocrud table structure.

It should be able to prefix the column names with an optional namespace.
the parameter should be passed via url ?prefix=test_data

it should be able to rename columns and add in calculated fields.
?rename=oldname,newname
?calc=newname,func(parameter)

it should be able to reuse osm ids or generate negative ones.
?osmid=fieldname

[James Michael DuPont]

It should be implemented as a catalyst plugin similar to autocrud

[James Michael DuPont]

We need another option to export it as a wiki page.
Also we need import tools for these formats as well.
