text zoom disabled on all webkit browsers

[calvinhsu]

As mentioned in this post:

http://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/font-size-fixed-under-webkit-browsers/

It is because of the following line in default.css of bp-default template:

-webkit-text-size-adjust: none;

Some searching shows that it's intended for text-size controlling on mobile device and touch screen, but it also prevents text-zooming on desktop browsers.

@media screen and (max-device-width: 480px), screen and (-webkit-min-device-pixel-ratio: 2) {

-webkit-text-size-adjust: none;

}

(In [5164]) Tweak the responsive CSS to fix text resizing on Webkit browsers. Fixes #3589. Props modemlooper
