Port Nautilus Properties Dialog to Use GtkBuilder

This Project is about using GtkBuilder to Construct the properties dialog for Nautilus. The result of this project would be that design Improvements and Modifications could be made without touching the C code, but only by editing the .ui XML file using GNOME Glade or GNOME Builder. Currently the Properties dialog UI is being built using C source code. Here the UI creation code is intertwined with the business logic of properties window, as a result of which applying design Improvements and UI modification becomes very difficult and cumbersome. This project would make it very easy to make UI and design changes for future improvements.
