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
Got angular frontend to render ads and allow edits

* Modified process.py a bit to make debugging and angular sorting easier
* Changed process.py to deal with strings slightly differently
* Modified UI by making things clearer and adding directions
* Ad text is missing some spaces at places where weird characters were removed
* TODO: Need to preview edited ads
* TODO: Need to add button to send edited ads to backend to send emails to members
