Hungarian translation ready + Translator helper tool

[lionkmp]

Dear Green developers,

I've completed the Hungarian translation in Transifex, please check if it could be included in the releases. (Mobile too, but I open the issue here on Qt version.)

I'll need to do some proofreading/testing when the text is in the software - no worries, I'll keep on maintaining it. I can test on PC and Android.

If someone could please raise my Transifex account to proofreader level, that will be useful to ensure quality. (blockstream_lion that is)

Translator helper tool

I had this little tool work in progress since a while, so I used it while working on Blockstream Green. Feel free to let translators know, if you think this is something useful. Useful for new languages mainly, because experienced translators can find the corresponding UI items probably. This tool helps finding context of text you need to translate. (Far from all text, but still useful.) (And it is work in progress (too), and I already have some more screenshots to add and features to upload.)
