Release 2.4.0 - Live translation feature WIP

This release contains a WIP version of a live translation feature.
The option defaults to off, but you can activate it by choosing a translation file and checking "Show live tag translation below prompt".
It will not affect the normal functionality if it is off.

It looks like this:

Example with Chinese since the idea came from Chinese users and I already had translation files lying around from testing. But it should work for any language, although I didn't test it outside of Chinese.

Clicking on a detected tag will also select it in the prompt for quick editing.

Known issues:

The translation updates when the user types or pastes text, but not if the action happens programmatically (e.g. applying a style or loading from PNG Info / Image Browser). This can be worked around by typing something manually after the programmatic edit.
