Building Rapidly

Now that I figured out how to do intersections, I've made rapid progress on other aspects of the next release. Since adding multiple roads and intersections makes the program more complex, I have to go through and modify multiple sections to accommodate them. So far I've updated the menu, the template load and draw routines, adding and deleting routines, and fixed a number of bugs I've spotted. Last to do is update undo/redo commands and modify the help file. So if all continues to go well, the next release should be ready by early July.
