Issue #1104 - Set the browser's opener when adding a new tab

- This modifies `loadOneTab` and `addTab` to accept an opener
- This code was adapted from Basilisk's copy of tabbrowser.xml without the refactored code changes (which is a lot more involved as it divides addTab's functions into multiple functions)
