Summary: This is an update of facebook/yoga#368 which was reverted. It fixes support for align-content: strech with multiple lines. The problem with the last attempt at solving this was that align-items:stretch was interfering. We handle this now by detecting when the flex basis of the children hints at them overflowing. This is not 100% correct as the size of the items could change when remeasuring but it will work in 99% of cases.
