Easier credits

I had made a note about common errors I saw with ep26's credits. Roughly ordered from most to least problematic (at least in my view :p ):

•   1. not translating anything
•   2. translating "beta readers" as "proofreaders", which is not the same thing: beta readers are for the script (and hence language independent), proofreaders are for the translation
•   3. spacing between the sections not in the same style as the original
•   4. forgetting small words ("and", "on ")
•   5. not translating the license (“Creative Commons Attribution” has an official translation in a lot of languages)

This is not the end of the world but the comic comes across a whole lot more professional if this is improved. For episode 26 I fixed the translations but it'd be nice if the problems could be avoided in the first place by making it easier for translators to get right.

Additionally,

•   6. @Deevad wanted to put some interesting content on the credits page so it's not just a place that people (have to) scroll through to reach the comments. These are the first ideas he shared:
  1. Two columns: one for credits, one for some bonus content (TBD)
  2. Easier translation: one text object for the categories, one for the names
