Various changes to address some performance issues

[time4tea]

Hi -

Related to zaproxy/zaproxy#9302

Here are a set of changes that addressed, for me, the serious performance issues I found trying to use ZAP to spider a website.

This, and the associated PR in the other project - transformed the system from a very slow thing with an unresponsive GUI to something that was very fast, and GUI was responsive throughout.

I appreciate that this PR is probably not something that can be merged in. However, I'm sorry that I don't have the time to split it, and shepherd it through a review process. However, it is offered as-is if it is useful.

The main changes are:

• See where some counters are updated a lot, which previously caused an immediate AWT Event, and instead defer these.
• Use Glazed lists for some table models - there is more that could be done here, this only was done for the tables i needed.
• Split out in some cases calls that cause AWT Event, and the actual AWT method - previously there were two different paths in one method depending on which thread.
• in Spider* try to understand how certain objects are constructed, and simplify - moving setXXX to constructor where possible - so objects were ready after construction.
• replace a use of URL (deprecated) with URI - which is much more performant.
• Update some tests where it seemed to make sense.
• Add some images (might not need to merge these) to show how the thread blocking looks before and after the changes here and in the other PR.
