[QBS] Functions in QBS scripts and accessing properties from them.

[Tim Hutt]

Is there no way to do this in two files instead of three? It doesn't seem
like I can put the `import YourFunctions` before the `Project`, so I need a
separate file for the Project and Product, and then a third for the
javascript. Is that right?

Cheers,

Tim
