FrequencyWeave Tabs door kpuc

This began as a clone of https://addons.mozilla.org/en-US/firefox/addon/sort-tabs-advanced/ but I changed it to weave tabs by domain, rather than group and sort them.

We created this addon for ourselves to redistribute "bunched up" domains over the set of tabs in a window. We take care to preserve the order the tabs are found in the window per-domain, as for webcomics that are not the "gag-a-day" sort could get out of order otherwise.
This bunching would happen if one adds the back catalog of episodes for a webcomic, or an rss aggregator groups by domain, etc.

A future version is planned where we can redistribute within a domain via regex (for example, webtoons hosts many webcomics by many artists, and within that domain we redistribute by frequency. We would want to make this configurable by the user in order to do so for other domains as well).
