Grid should allow empty "include" parameter
-------------------------------------------

                 Key: TAP5-1143
                 URL: https://issues.apache.org/jira/browse/TAP5-1143
             Project: Tapestry 5
          Issue Type: Improvement
          Components: tapestry-core
            Reporter: Geoff Callender


I wanted to create a grid with only one column which is a synthetic property, so I specified include="" add="syntheticProperty", but the include parameter cannot be null. 
Instead, I had to exclude all of the source's properties, eg. exclude="propertyA, propertyB, propertyC" add="syntheticProperty", which is brittle because it will misbehave if the source is given any new properties.

Here's a live example: http://jumpstart.doublenegative.com.au/jumpstart/examples/onepagecrud
