Blank line between block definition and first block element

[dylanlerch]

If a block only has block as children, a blank line is written before that first block. It looks something like this:

step "Run a Script" {

    action {
        ...
    }
}

This is minor, but it would be good to remove this to keep files a little more compact. We would still want to keep this newline between any attributes and the first block (like shown below), but if there are no attributes the block should start on the first line.

step "Run a Script" {
    properties = {
        Octopus.Action.TargetRoles = "Cloud"
    }

    action {
        ...
    }
}
