Explorer for finding words to edit

[arrocke]

Translators need to be able to find words to translate, and open them in an editor.

• [x] (@ilearner777) The first thing we want to try is building a tree view to search for words. It will have the structure:

  hebrew | greek
  list of first letters
  list of first and second letters
    list of words that start with those two letters

• [ ] Then we can add trees for the lexical and contextual domains for each language, to quickly see what words are associated with each domain

Some other functionality to consider:

• Indicate the status of each word so you can scan the tree to see which words have already been translated.
• Alternative actions to open in preview, or open in a different reference language other than the target language
• An action to open the history of translations
