Trello Card Aging

Provides some features for Trello, related with the card activity:

- Last activity
Creates an indicator at the bottom of the card, that shows the time difference between now and the last activity of the card.

- Card age
Creates an indicator at the bottom of the card, that shows the time difference between now and the card creation.

- Aging effect
The aging effect is the same as the one provided from the Card Aging power-up, except for one detail: In the official power up, the card aging is removed if someone just change the card position (drag and drop) inside a list. This extension considers the last activity of the card, what might be a comment, attachment, anything who left a log inside the card.
The aging is applied in 3 states, at 7, 14, or 28 days without any action in the card.
