QNX: Adding native file dialog support for Blackberry

This patch enables use of native file dialogs in the application
modal case.

The native file open dialog is reasonable but the native file save
dialog could do with some improvements to make it more usable.
Perhaps providing our own "native" dialog UI would be an option
once the widget style is finished.
