XML export

There's a new option under the Save As dialog box, to export your topology to an XML format. The supported schema can be found here. This is the NRL EmulationScript NetworkPlan with time 0 location information. Note that this format will see some updating as the spec evolves.

Sample output for two router nodes linked together is shown below. There is still much to be done in order to represent all of the data contained in the imn file format.

The XML export occurs at the Python (cored.py) level, with the GUI feeding the back-end the filename to write. This was done so that Python-scripted scenarios could be saved/loaded directly to/from XML without the GUI.
