Create Dialogues Content Database Backend

[inoftrobinson]

Should have :

• [ ] Multi page navigation

DynamoDB search based on :

• [x] Characters names in a scene (sort on presence of string in a list)
• [x] Text content in dialogues

DynamoDB sorting based on :

• [x] Date of creation (sort timestamp)
• [x] Date of last modification (sort timestamp)
• [x] Section Instance Id (sort on an int/id)
• [ ] Status (possibility to have as much custom status as possible, like "in_writing", or "need_to_be_record" or "need_to_be_edited" etc) (sort on string or int/id that represent the status)

Front end :

• [x] Search by characters names & text search
• [ ] Sorting selection (date of creation, date of last modification, section instance id, status)
• [ ] Make that the text editors are reloaded when the html is changed after changing the text to display

Other things :

• [x] Update content in the database when its modified in the interface
• [x] Update lastModifiedTimestamp when a content element is modified
• [x] Core Botpress to Inoft Vocal Engine conversion
• [x] Interface in the menus to import data from Botpress to the Inoft Vocal Engine
• [ ] Give a warning when importing data and possibility to keep existing or override data if the Ids of some elements are conflicting
• [ ] Delete data from database in the interface (half delete, keep in "archive mode", and keep in database with a special status)

Modified the Database Client in order to have it create the secondary indexes in a DynamoDB table

These functionalities have been moved to the inoft_vocal_engine, and are not for the inoft_vocal_framework (i'm just finishing up all the capabilities for this issue)
