Support for the creation of translations using Qt Linguist

[elsandosgrande]

This is more of a long-term goal.

Olive is one example of a Qt application that uses Qt Linguist that I'm familiar with. Here are its instructions for contributing translations: https://github.com/olive-editor/olive/wiki/Translations

Qt's own manual for Linguist: https://doc.qt.io/qt-5/qtlinguist-index.html
It also seems that Qt has some example code in its online documentation as well: https://doc.qt.io/qt-5/examples-linguist.html

I can personally contribute Bosnian, Serbian, and Croatian translations when time allows it.
