Ensure compatibility with LIFT from The Combine

[imnasnainaec]

FlashGrab explicitly handles LIFT files from FieldWorks or WeSay. However, WeSay is no longer maintained and The Combine produces LIFT files that are compatible with FieldWorks. It would be nice to

• Make sure exports from TheCombine can be imported directly with FlashGrab
• Update documentation (READMEs, comments, and Wiki) from "FieldWorks or WeSay" to "FieldWorks, The Combine, or WeSay"

@imnasnainaec Could you send me (on Slack or by email if private, or attached to this issue if public) some LIFT files generated by The Combine? I've got my head wrapped around the FlashGrab source right now, at least a little, so I can go ahead and test them and see if they work. And I can probably make the necessary changes to FlashGrab as well.

And while I'm at it, one question. FlashGrab looks at the name of the exported LIFT file to determine the FieldWorks project to look for when it's looking for media (audio and/or pictures) to import. Where does a typical installation of The Combine keep its projects and media files? Perhaps I can update the FlashGrab code to look for media files in the right storage location for The Combine projects, if it can detect that the LIFT file was generated by The Combine rather than FLEx.

As for updating docs, go ahead and tackle that one yourself since you know The Combine much better than I do and you're better placed to give step-by-step instructions for exporting a LIFT file from it.

Thanks @rmunn. Here are the LIFT files we use for testing The Combine: https://github.com/sillsdev/TheCombine/tree/master/Backend.Tests/Assets, each zipped folder contains:

• a *.lift file
• a *.lift-ranges file
• a WritingsSystems folder
• (optionally) an audio folder

It's the same as the result of a LIFT export from FieldWorks.

Since the zipped folder is exported from The Combine on the web, the typical location is the downloads folder. :) So instead of looking in some default path for a matching project, we'd probably need one of the following:

• FlashGrab to know the path of the uploaded file, so it can pull from the safe folder
• FlashGrab to take a folder that contains a .lift file
• FlashGrab to take a zip of a folder (or a folder of a folder) with a .lift file
