Created translatable strings for fuel types, crossings, entrances and substations

[Miroff]

1. Created list of translatable values for fuel types based on Wiki
2. Created limited set of values for RU based on discussion in local community. This set contains only fuel types used in the Russia.

If this PR was merged, I'm going to create similar preset for Belarus.

This would fix #404.

I've tweaked this quite a bit and finally merged as 95c206b (sorry for the extra commits in your main branch @Miroff). I excluded the crossings field, as that is now handled in #590. I also changed the way the localized fuel field works: instead of duplicating the preset for every region, I made the field region-specific and let it inherit the strings from the global field. That avoids that translators have to translate the same string more than once, and should scale pretty nicely if you want to add more countries. Further, I removed lesser used fuel values (cut-off approx ~1000 usages with exceptions for the H2 types) and reworded the substation value strings slightly.
