Fix #210 Recreate Ruby's line breaks in Puts

[Eneroth3]

I may have a fix for #210.

Without TestUp puts [1,2,3] outputs as:

1
2
3

Without TestUp it outputs as [1, 2, 3].

This fix restores the default Ruby behavior to puts for Arrays.

Not sure if there are other classes affected, or if there is a more generalized way to swap out to_s on the line line = arg.to_s to make the method always act as native Ruby puts.

I'm also not sure if this proposed fix has other consequences for TestUp and Minitest, or if there is a completely different way to address this architecturally in such way that we don't have to override puts.

Also wondering if there's a reason for using for. each seems more common but I don't think there is any difference other than cosmetic here.

That probably stems back to when for was faster than each.

Actually, that's not Ruby's own default. That's SketchUp's version of it. I just checked with irb:

irb(main):002:0> puts [1,2,3]
1
2
3
=> nil

It's been bugging me that SU output data differently from Ruby. Wishing it was more consistent with Ruby. this is probably why TestUp behaves like that. (Stating to remember there might be a reason for this behaviour.)

I've been meaning to propose that we clean up SU's console to act more like Ruby's console output.

It could be. I might have corrected the console output via TestUp such that it played better with Minitest and its reporters. (My memory is a little fuzzy. But I think there was some issue I ran into with SU's non-standard formatting.)

We want to make SketchUp's output mirror Ruby's own output. It ensures that using other tools/gems from the Ruby ecosystem prints things equally. Closing this as we want to eventually take the TestUp monkey patching and integrating into SketchUp itself.
