Set up for Hungarian translations

This issue is to track progress on setting up for translations into LANGUAGE.

Tasks:

1. [DONE] Add a new issue component for translations into this new language, by editing the Project page. The component should be called "HU translation".
2. [DONE] Make a new source/hu directory. Copy all of the source (English) files, including the images subdirectory, into the new directory. Keep the file names and IDs the same as they were in English.
3. [DONE] Add a new section to the _attributions.txt_ file for the translation team management for this language. Template:
   

   ==== Translation into LANGUAGE_NAME
   
   The LANGUAGE_NAME translation of this guide was coordinated by:
   
   * https://www.drupal.org/u/person1[Person One]
   
   * https://www.drupal.org/u/person2[Person Two] of http://example.com[Company]
   

4. [DONE] Make a separate issue for the screenshots. See Guidelines document for issue template.
   #2798661: [HU] Hungarian screenshots
5. [DONE] Grant issue maintainer and VCS commit permissions to the manager or managers of the language team for the new language, by editing the _Maintainers_ page for the project.
6. [DONE] Make issues for translating each topic into the target language. There is a spreadsheet file scripts/bookmarks.fods that will aid in doing this.
7. [DONE] Add hu to the build scripts in scripts/languages.txt, and verify that it builds without errors.
8. Optional but recommended steps:
   • [DONE] Make a translation glossary for this language. File scripts/TermsToTranslate.fods is a good starting point. This should be located in a place that the language team normally uses for communication, such as on localize.drupal.org.
   • [DONE] Make a shared spreadsheet (for example, using Google Sheets) to track translation progress. File scripts/bare_topic_names.csv is a good starting point; you can add columns for the issue URLs, and status of each issue.
9. Start translating!
