Vertical tab / sidebar expand on hover: adjustable wait time

[moonjur]

After a few days of trying out the vertical tabs with "expand on hover" enabled, I noticed that the time it takes to expand the tabs feels unnaturally long. For one, it's nice that if my mouse accidentally hovers over the sidebar, it doesn't automatically open it, but adding the option in about:config to change the hover time needed to expand the sidebar would help in making the hover time feel slightly more natural!

I have the oppositw feeling, "expand on hover" feels too quick to me - I'd actually prefer the sidebar to stay close when I hover to change tab, and open when I stop for a longer time to search the right tab to click on. 

The proposal to add an option to change the time to open could fix both needs.
