Add flag to gracefully continue if source .yaml files don't exist

[rick-cti]

Currently, if a .yaml file defined in master.yaml does not exist, the configurator:run command fails with an error message:

Could not find file in path /path/to/my/file.yaml

Is it possible to add a command line flag (such as '-i', or '--ignore-missing-files') so that configurator:run just outputs a message to say it's skipping the missing file in this scenario, then proceeds with the rest?

@rick-cti I've put a change in the next release of Configurator to add this feature.
