Changed all intermediate file outputs to save to output folder

Allowed for custom output folder, returned Dockerfile to work under user account and port 7860

Now checks for output folder before saving. Minor code cleaning

Fixed cleaning for semantic search. Handles text with backslashes in (if cleaned). Updated packages. requirements file for only keyword search added.

Improved code for cleaning and outputting files. Added Dockerfile

Cut out semantic search temporarily while issues with Jina gated model resolved. Improved error/progress tracking and messaging. Placeholder for Spacy fuzzy search.

Better error checking. Doesn't load in embeddings file twice now.
