Script dryrun

[gergness]

• Allows ... in runCrunchAutomatio() so we can use the dry argument (and later dry_run when the API is updated)
• Allows passing multiple scripts, which are then concatenated. I think this is particularly important for dry runs because the validation would need to be cumulative.
• I couldn't resist subtracting out the line numbers for multiple scripts, we can undo it if you really want, but I don't think it's that hard to avoid the off by 1 error, and being able to jump right to errors in their original file when running runCrunchAutomation(list.files(), dry_run = TRUE) is a huge UX improvement.
