Progress converting codebase to C++

I've begun working my way through sodipodi making everything work with g++.

At this point I have done: libnr/* libnrtype/* inkscape.c Not complete, but partly working: helpers widgets

To test, just change the CC=gcc line in the makefile and make clean && make the aim is to have inkscape compile both in gcc and g++.

The biggest problem is _(). most effort has been fixing variables named 'new' and 'class' and sorting out the various string types.

I also found a bug thanks to the type system (two params swapped) :).

Inkscape Forms!

A group of Sodipodi developers establish the Inkscape Project to pursue creation of a fully SVG-compliant open source editor and to continue the logical development of the Sodipodi codebase in this direction.
