SharpDevelop improvements(1)

Hey everybody,

SharpDevelop is at 4.1 pre-alpha and some of my contributions are inside.

These are:

- WPF breakpoints pad with code completion

- WPF bookmark pad

- WPF watch pad with code completion

- WPF local vars pad

- change Reflector path in Options panels.

- spell checker based on (N)hunspell - this addin is not inside the release but you can find it on my github.

The next improvements concerns pin data tips and edit value in debug tooltips.

Give #D a try! :)

Happy programming!
