Collection order

[reinij]

Modify collection order to follow the collection list in the properties file. Now it seems to be random at least with Geopackage as a data source.

An example:
collections=aita, allas, ankkuripaikka, autoliikennealue, avoin_metsamaa, building_installation, eramaa_alue, erityisalue, esterakennelma, harva_louhikko,...

and in HTML

This is due to FeatureServiceConfig #getCollections returning the values from a HashMap where the order is not "random" (it doesn't change per request) but it's not alphabetic or the insertion order either. Fixing this is very easy.

I'm assuming the expected order would the one that appears in configuration (and not alphabetical), e.g.
collections=z, x, y
Would return

• Z
• X
• Y

This sounds as a reasonable fix.
