bacon v3.21.0

• add new line format template variables: {job} and {item-idx} - Fix #423 - Thanks @cehteh
• add the show-item action, which scrolls the output to an item to reveal it - Thanks @cehteh
• rerun job on undismiss
• !pattern syntax in the ignore config field to override gitignore rules - Thanks @ishad0w
• improved top item sticking (bacon is more often keeping the same item on top on recompute)

Users of nvim-bacon should update it and modify the export format to the new suggested format to have bacon show the item focused in nvim (it still works as before if you update only either bacon or nvim-bacon).

Users of emacs should have a look at this emacs minor mode: #422
