Make the source tab hover effects feel more responsive

[darkwing]

This is just a rough proposal. My opinion is that the tab hover transitions are slow and appear labored. The labored feeling is due to speed, so I drastically sped up the transitions and they seem much more quick and elegant.

I know the project has loads of transitions so I guess I'd like to hear some opinions on this faster effect and see if we'd like to speed things up globally.

hi @darkwing! thanks for the proposal, do you happen to have a screencap of the change?

hm...now that i think about it, i guess showing transitions with gifs doesnt work all that well.. 🤔 ill pull and take a look in a little bit!

@darkwing When I was implementing the Modal transition, I was pointed to this document http://design.firefox.com/photon/motion/motion.html Using the curve and 150ms would be a good transition time I think.

Updated to .15s. Still think the lower speed seems nicer but branding is important.
