Description of change

1. Allow customization of the default vastContentAsUrl=true value in the config
2. Allow global (as opposed to per-bid) targets to be set in the config

                pbjs.setConfig({
                    debug: true,
                    adhese: {
                        vastContentAsUrl: false,
                        globalTargets: {
                            tl: ['all'],
                            ab: ['sometestvalue']
                        }
                    }
                });

• test parameters for validating bids

{
  bidder: '<bidder name>',
  params: {
    // ...
  }
}

Be sure to test the integration with your adserver using the Hello World sample page.

@mefjush I've approved the code changes, but I'm not sure why the Circle CI tests are always failing. Can you merge the latest from Prebid master into your branch?

@msm0504 The build looks better after merging the latest master indeed.
