CKEditor plugins for TMGMT

The Translation Management Tool (TMGMT) module is an extension to support editors, publishers, translators and project managers during their process of content translation. Since I think that Local Translator is a very useful submodule, there are still lots of things missing. The tool was working in Drupal 7, but it was rather limited in functionality and by far not fulfilling expectations of professional translators. I believe the next goal is to make the Local Translator a professional CAT Tool and I would like to help with implementing CKEditor plugins using Javascript. Because TMGMT wants to use the CKEditor libraries to build an alternative non-WYSIWYG translation editor, I would propose to implement some special linguistic actions like defining segments, marking them in the UI and masking specific HTML tags.
