About dialog improvements

[Don-vip]

I think our About dialog can be improved in several ways:

• First it should be resizeable as README, LICENSE, etc... do not fit in the default window -> Easy
• Then, the README, REVISION, CONTRIBUTION and LICENSE could be translated. Too complicated
• We should make the translation more prominent

Replying to Don-vip:

Is there an easy way to add these files into our Launchpad translation system ?

Yes, adapt the scripts in the i18n directory. There are several sources, where additional strings are added from for translation (e.g. presets).

But find a way to split the texts. Large texts need to be retranslated completely when a minor bit changes.

If the last one works this is fine 🤗

I'm curious, it looks like magic.

It seems to have triggered something on Launchpad: all translations have been updated today!
