Sort devices by name and OS version

[hallc]

The list of devices on the build template editor is not sorted by name or OS version. Our Xcode server has quite a few simulators configured and it's difficult to pick out the ones we need to test a particular project against.

Sorting by name and OS version would make the list easier to read.

I can gladly submit a PR if this is a welcome change.

Hi @hallc,

thanks for taking time to report this. I wrote a function to somehow sort the devices ages ago and it's possible it doesn't work properly since my big refactoring for 0.6. It's this function, so feel free to make sure it works as you'd expect and contribute a PR!

Thanks!
