Add action keywords for each plugin (#6129)

* Add action keywords for each plugin

- Added keywords for each plug-in
-  Change window walker search to use Query, not RawQuery (to get rid of action keyword)
- Make sure plug-ins that have action keywords as well as are in global list don't get added twice

All tests passed that passed before I started

Addressing issue #5823

* Fix bad formatting from the merge

* Do not add global plug-ins if we have an action keyword

Note side effect: you will not not be able to search for things that start with one of the plug-in keywords.

* Missed merge conflict repair!

* Revert "Do not add global plug-ins if we have an action keyword"

This reverts commit e3b0ecd708.

* Adjust keywords to suggested ones

* No need to ubild a query if we aren't going to use it

Didn't quite get the if statement right the first time I put it in.

* Do not add global plugins if we have an action keyword

This means, especially without a space, that global plugins do not become part of the search. Which really narrows down the search results, nicely.

* Update keywords as requested in the PR
