gd translation update - shortened some strings
Let's see if this fits. I also found 2 bugs:
- When episode is not available in a language, the first/last/back/forward navigator switches to English
- https://www.peppercarrot.com/gd/files/webcomics.html - left-hand navigator is in English
Running xgettext & msgmerge might fix some of that.
The diff is rather big because the file comes from a different editor program now.
