Implement park rendering at z4-5 ( #1160 )
...
Unblocks ZeLonewolf/openstreetmap-americana#51
Currently, OpenMapTiles renders protected areas at zoom 6 and higher. However, the western United States has protected areas that are so vast that it makes sense to render these areas as low as zoom 4, as noted in ZeLonewolf/openstreetmap-americana#51
This PR extends the generalization of park features from its current termination at zoom 6 to zoom 4.
Here is an example from the Americana style of rendering protected areas at zoom 6, which is currently the lowest supported zoom:
https://zelonewolf.github.io/openstreetmap-americana/#6/45.313/-111.721
We would like to provide rendering at zoom 4 (no labels) and zoom 5 (with labels) in the Americana style. Below are samples generated from this PR for Idaho, USA:
Zoom 4:
Zoom 5:

Add `boundary=protected_area` parks
...
Update the **class** of the **park* layer in a backward-compatible way.
The class for `boundary=protected_area` parks is the lower-case of the
[`protection_title`](http://wiki.openstreetmap.org/wiki/key:protection_title )
value with blanks replaced by `_`.
`national_park` is the class of `protection_title=National Park` and `boundary=national_park`.
`nature_reserve` is the class of `protection_title=Nature Reserve` and `leisure=nature_reserve`.
The class for other [`protection_title`](http://wiki.openstreetmap.org/wiki/key:protection_title )
values is similarly assigned.

Use one pass docs image generation ( #751 )
...
quicker and cleaner diagram image generation.
Remove etl-graph and mapping-graph targets - redundant
Also, the obsolete "fields" is still in Imposm's code and both names are accepted,
but "fields" is not documented anywhere (PR submitted), and could be removed at any moment.
Our docs were not supporting it until this PR, so renaming it at the same time.
Several images have been updated due to a more inclusive mapping scan

Use _resolve_wikidata in layer mapping.yaml ( #731 )
...
Mark all tables that should not be populated with the Wikidata
international labels with a special OMT-specific flag.
This should be ok to merge even before the new tools version
is used because imposm seems to ignore anything it doesn't understand.
The next tools version will remove it when generating imposm mapping file.
