Insufficient spacing between Dev-Dependencies and Versions

[mrmonday]

Looking at: https://crates.io/crates/pnet_macros/

Using Firefox 42.0 on Linux:

You'll notice that the formatting makes it look like the dev-dependency pnet_macros_support requires a version >= 0.10.6.0, since there is insufficient spacing between the two columns.

Yup, this still happens and pnet_macros is still a pretty good way to reproduce this. I had to play with the browser width a bit but found a width that produces similar results:

This'll involve adding some sort of forced spacing in between those two sections-- I'm not that great at CSS, so I'm not sure if margin or padding will be best, or if there's a way to handle it with flexbox.

Also doing a little cross-browser testing at various widths (firefox, chrome, ie, safari?) would be A++++!
