Subject: [PATCH] gui: Sort languages alphabetically (fixes #3813)

This change sorts the language selection menu in Syncthing's home page so
that the languages are displayed alphabetically. The issue was discussed in
#3813. There were few ways of doing this. Sorting the language names in
transifix file did not work due to access control. So I sorted the languages
directly in languageSelectdirective.js by inverting and sorting the language
info retrieved from localeService.js.
