add GeoHack with local map/lang support

[tankaru]

(1) With lang and region: https://geohack.toolforge.org/geohack.php?language=de&params=48.137222222222_N_11.575555555556_E_region:DE

(2) Lang only: https://geohack.toolforge.org/geohack.php?language=de&params=48.137222222222_N_11.575555555556_E

I think (1) is friendly.

Region is not obtained from browser. I use option (2).

Hi, I get language=de-DE instead of language=de with the current plugin version 1.5.0. Unfortunately, Geohack does ignore the de-DE value, it only understands de. Furthermore, adding region:de significantly improves the result, as mainly german maps are displayed then. Would it be possible to just use the language as region?

I have asked for this to be fixed, at https://www.mediawiki.org/wiki/Talk:GeoHack#Language_fallback

Language is not region; consider Spanish in Mexico or Portuguese in Brazil
