Add cookie support

[CJGlitter]

Problem

Slack changed their auth method to require cookies, breaking the functionality of this project

Solution

Switch to Emojme v2.0.1 to enable cookie support, add handlers for cookie as an additional parameter

Future fixes

• generate.sh: Add logic to support either option:
  • ./generate.sh "$NAME" "$SUBDOMAIN" "$TOKEN" "$COOKIE"
  • ./generate.sh "$NAME" "$AUTH_BLOB"
• generate.js: I updated the generate.js file to handle parsing the JSON object and using the cookie, but I did not make it functional. I figure that will be a cleaner solution down the line so I wanted to build for the future.

Notes

I ran another generate for your emojis to grab your latest list in case you didn't grab it when you left BT. Included yours in the README and emoji/ directory.

@jackellenberger it won't let me request a reviewer on the side panel here, but it's ready to go!

Just realized I should probably add some logic to support just the auth-blob when using the sh file. I can add that as a future fix.
