Batch#submit_string should pipe script to stdin of Open3.capture3

[ericfranz]

Instead it creates a temporary file and passes the path:

pbs-ruby/lib/pbs/batch.rb

Lines 300 to 307 in 7ce6f96

	# @return [String] the id of the job that was created
	def submit_string(string, **kwargs)
	Tempfile.open('qsub.') do |f|
	f.write string.to_s
	f.close
	submit_script(f.path, **kwargs)
	end
	end

I am not aware of how to submit a script from stdin through a library call. And writing it to a temporary file followed by a job submission through qsub or the library works in both cases. So I found it unnecessary at the time to handle both cases in different manners.

Did you experience any issues with this? If so I can definitely handle things different depending on mechanism used to submit jobs.
