- Improvements on document uploads (accept other files than html-files when entering a URL)

- Introduction of API-functionality (to be continued). Deduplication of document and url uploads between views and api.
- Improvements on document processing - introduction of processor classes to streamline document inputs
- Removed pure Youtube functionality, as Youtube retrieval of documents continuously changes. But added upload of srt, mp3, ogg and mp4
