Translation file imperfections

[EverGreenCoinDev]

Some of the translation files are incomplete and/or inaccurate. Review and modification of the Qt translation files will be performed and, whenever possible, by native speakers. For example, 450201d
This will also include adding translations to previously untranslated text.

I'm working on setting up a zanata project space to help coordinate translation collaboration.
