Trello Card Numbers

Description

This adds card numbers to Trello cards to help when viewing/discussing boards with a group of people. Trello actually includes card numbers but hides them by default.

This extension does the following:
- Reveals card numbers on cards themselves
- Reveals the card count for a given list
- Adds a card number to a created card
- Adds a card number head in the detail view
- Allows you to make card numbers bold
- Allows you to change the color of the card numbers
- Optional "Copy details" button for copying number and card title

This project was based off the widely available bookmarklet for Trello numbers mentioned in their forum at https://trello.com/c/PkIrgKzd/36-show-card-numbers.
