Azure Resource Manager template language additions

Here are some new changes in the Azure Resource Manager template language:

• Deployment outputs now support the condition property to help avoid deploy-time errors from conditional resources (documentation and sample).
• The copy() function will support non-object string inputs to produce an array result (documentation and sample).
• The newGuid() function will generate a globally unique identifier each time a template is deployed. This function is not idempotent and can only be used as a defaultValue on a parameter (documentation and sample).
• The utcNow() function will return the dateTime() in UTC, and the return value can be formatted using dotnet standard strings. This function is not idempotent and can only be used as a defaultValue on a parameter (documentation and ​sample).

These changes are now available in all public regions.
