Enable "Default" container for any outside links

[frontyard]

Before submitting a bug report

• I updated to the latest version of Multi-Account Container and tested if I can reproduce the issue
• I searched for existing reports to see if it hasn't already been reported

Step to reproduce

1. Click on any link that will open Firefox
2. Link is not opened in a container unless that site was marked with "Always open this in a Container"

Actual behavior

Link is not opened in a container unless that site was marked with "Always open this in a Container"

Expected behavior

It would be nice if we can set default container for any and all links not already bound to one of the containers.
