Create a new component <Conditional> for report

[sudhacheran]

To make the template easier for a non-programmer to write, create a new component with a single property called condition that resolves to a boolean. If the condition is true, the Conditional's children are shown, otherwise it renders as null. It could be used here as:

< Conditional condition={props.data.comments_ductwork} >
Ductwork Comments: {props.data.comments_ductwork}
< /Conditional >
There might be few other places in the templates where this component could be used.

Note, this can't be used inline. In particular, you can't use it inside of a table.
