File dialog for importing RAPID model to create new project should filter for .zen and .rapid files

Reported by @daffinm in ZEN-1960.
File dialog for importing RAPID model to create new project should filter for .zen and .rapid files. Currently shows all files. I can select anything, and if its not a zen model I get an error (obviously).

@tfesenko The file import dialog on windows does not filter for RAPID files. It shows everything, and the filter dropdown does not allow me to select a RAPID specific filter. So I can still get an error by selecting a non-RAPID file.

Just spoken to @tfesenko. Apparently this issue is not fixed yet and it may not even be possible to fix it.

All other integrations (Swagger, API Blueprint and RAML) behave the same way as ours.
Ready! API is not open-source and basically is a black box. I posted a question to their forum - http://community.smartbear.com/t5/Ready-API-and-SoapUI-PlugIn/AFieldType-FILE-in-a-com-eviware-x-form-support-AField-set/m-p/116293#M273 .
