v0.0.7

- DONE Reference missing bindings in documentation
- DONE Upgrade version
- DONE Improve the error message around the setup (the setup message is too generic and must be more detailed)
- DONE Save the buffer after the synchronization is done (after all we write the trello ids in the buffer)
- DONE Release

@sw1nn I finally decided to also improve the error messages regarding the errors you mentionned.
