This commit adds the ability to inject entity-based plain CSS filters and also a set of the most commonly used entity-based scriptlet injection filters. Since the scripting API is not compatible with entity patterns, the entity-related content scripts are injected in all documents and the entity-matching is done by the content script themselves. Given this, entity-based content scripts are enabled only when working in the Complete filtering mode, there won't be any entity-based filters injected in lower modes. Also, since there is no way to reasonably have access to the Public Suffix List in the content scripts, the entity-matching algorithm is an approximation, though I expect false positives to be rare (time will tell). In the event of such false positive, simply falling back to Optimal mode will fix the issue. The following issues have been fixed at the same time: Fixed the no-filtering mode related rules having lower priority then redirect rules, i.e. redirect rules would still be applied despite disabling all filtering on a site. Fixed improper detection of changes to the generic-related CSS content script, potentially causing undue delays when for example trying to access the popup panel while working in Complete mode. The scripting MV3 can be quite slow when registering/updating large content scripts, so uBOL does its best to call the API only if really needed, but there had been a regression in the recent builds preventing uBO from properly detecting unchanged content script parameters.
