wxSF 1.6.1 released

wxShapeFramework version 1.6.1 has been released today. The main changes are:
- new wxSFGridShape has been added,
- new wxXS 1.1.6 is used,
- connection lines can be docked to any point of shapes (thus line arrows doesn't point strictly to the shape's center anymore),
- wxSFControlShapes has been improved and fixed,
- wxSFDemo and wxSFSample4 projects have been improved to demonstrate new features,
- some important bug fixes have been applied.

For full list of the changes see the change log.

I'd like to thank to those people who reported bugs and proposed new features. Please, feel free to let me know what a feature your are missing in the library or what is broken. Any feedback is helpful!
