Accuracy improvements to mouse move. (#168)

* Accuracy improvements to mouse move. There is some nuance around the dispatching of mousemove and pointermove events that seems a bit arbitrary, but we do want event accuracy to be as close as possible to human interactions. Therefore, I've changed drag.js to only dispatch mousemove events during jQuery drag and drop on PointerEvents-type browsers. This appears to correctly emulate human-user event generation. Though I'm not sure why human users do not generate all events.

* Updating yml to use a newer version of firefox. Expected events changed in v 59. Travis is running v 56. Current is v 64.

* Disabling a testpoint because it seems to sporadically fail on linux. At the end of the test,the cursor does not leave the final box, according to the test script. But it seems to sporadically leave, perhaps from a loss of focus. In any case, I'm removing the final testpoint because we want the testbed to be reliable.

* Fixed typo that would cause two bool fields for detecting html5 drag. It would make no difference to test stability or functionality, but its confusing and wasteful
