Jira Agile Cards Maker - Version 0.8.7

- FIX: fix display issues with long project keys
- FIX: printing a single card with many sub-tasks meant that the browser chopped tables in half, due to the container being set as inline-block, this is now fixed
- FIX: printing a single card now disables headers/footers in Chrome (only)
- CHANGE: changed from using a pure css approach to sub-task item overflow to javascript as chrome does not support rtl direction text-overflow
