[xdot] new feature to have multi_line clickable support patch inside

[GoogleCodeExporter]

example in:
http://code.google.com/p/xdot-multi-line/

* Explanation
-------------
with this feature you can asociate earch line of a node with a part of the url.
in the file in main.cpp we have:
1 class A {
2    int hello;
3    int world;
4 };

and in the graph appears a node A with 4 lines:
A
_
- int hello
- int world

if you click in "A" you obtain the first part of the URL: 
main.cpp:1

if you click in "-int world" you obtain the fourth par of the URL:
main.cpp:3
