20902	[Patch] Warn about solo layer and level tags	skyper	Klumbumbus	"==== What steps will reproduce the problem?
1. Have an object with only `layer=*`
1. Run validator

==== What is the expected result?
A warning about missing tags

==== What happens instead?
No warning except for relations

==== Please provide any additional information below. Attach a screenshot if possible.
Please, find attached [attachment:josm_combinations_only_tag.patch patch] which adds `layer` and for ways and relations `level`. I am not sure about node and a solo `level=*`.
I introduced a class to warn about relations with `type=*` and one more tag, as there is already a warning about relation without `type`.
