got file uploads to work somewhat. changed edit page and some other things
added search and limit num results to email edit page
switched to getting upload filenames and passing them to python
* async read/write was causing problems so I tried using promises
* promises were annoying and so was sync read/write
* ended up ditching read/writes and just passing filenames
* this is simpler and faster
updated node version due to Oct 18 security vulnerability. updated versions for npm, etc too
made some modifications to link process.py to node backend
temporarily disabled access codes for faster development
