ScrummerTheodo

Adds Story Points, Post-Estimation points and card IDs to Trello.

Heavily based on rickpastoor's amazing and lightning-fast Scrummer. Use rickpastoor's Scrummer if you need subtotals inside a list, using separators, or if you don't need post-estimation points.

Features :
- Pick Story Points and Post-estimation Points from inside the card.
- Shows story points and post-estimation points for each card, a total for each list and for the board.
- Shows the card number on the board.

Uses no external library for optimum speed.
