Fix #262 #263 - Handle Path Arguments (QFileDialog)

[jmarrec]

• Fix Add file system browse control for measure path arguments #262
• Fix Cannot enter path arguments in apply measure now #263

The OS SDK / BCL-gem implementation of the path arguments is incomplete and confusing, and they don't handle the makePathArgument arguments:

• isRead. what does that even mean? Is this assuming that this is for reading meaning it must be 1) a file (not a directory) and 2) it must exist?)
• extension

here is my test measure

example_path_argument.zip

  # define the arguments that the user will input
  def arguments(model)
    args = OpenStudio::Measure::OSArgumentVector.new

    isRead = false
    extension = "CSV (*.csv);;Excel (*.xls *.xlsx);;All Files (*)"
    required = true
    modelDependent = false
    output_path = OpenStudio::Measure::OSArgument.makePathArgument('output_path', isRead, extension, required, modelDependent)
    output_path.setDisplayName('Output Path on Disk')
    args << output_path

    return args
  end

  # define what happens when the measure is run
  def run(model, runner, user_arguments)
    super(model, runner, user_arguments)  # Do **NOT** remove this line

    # use the built-in error checking
    if !runner.validateUserArguments(arguments(model), user_arguments)
      return false
    end

    # assign the user inputs to variables
    output_path = runner.getPathArgumentValue('output_path', user_arguments)

    puts "output_path=#{output_path}"

    File.write(output_path.to_s, "hello")

    # report final condition of model
    runner.registerFinalCondition("The output path is #{output_path}")

    return true
  end

Default to something sensible for now

Without this you, you get valueAsString, and it gets quoted in the workflowJSON as

    "my_path_argument": "\"/the/path/\""

and when you run, Ruby for eg can't understand it.

TODO here. Basically I think OS SDK should store it as a readable format, and we can reconstruct a proper Qt files Filter from it.
