attachment: together does not work as expected if attachment width greater than target width

If the attachment width is greater than the target width the attachment: together constraint doesn't act as expected. It should essentially have the opposite behavior.

This is also a problem for me, using tether to create tooltips that describe smaller elements.

I've opened a PR (referenced above) that I believe fixes the problem; looking forward to any constructive feedback from Tether maintainers.

@alexf101 I created this one already - #225

😖 sorry, didn't think to look for one. Looks like we both had roughly the same approach though.
