Timon Kruiper 6a15d668ee Change the default stdin behavior of RunStep to .Inherit
This behaves the same as stdout and stderr behavior which also
default to .inherit. Also adds a field to RunStep to change the behavior.

Since this is a breaking change, previous behavior can be restored by doing:
`RunStep.stdin_behavior = .Ignore`.
