DSL support for host window

[brianberns]

FuncUI is a great way to build Avalonia apps, but one difficulty I've encountered is that there is apparently no way to manage the main window via the DSL. Some examples:

• Key bindings. I created custom properties for building key bindings, such as KeyBinding.gesture and KeyBinding.command, but there is no way to attach them to the main window. Instead, I ended up creating an invisible top-level Border control that grabs focus and implements the key bindings. Ugly, but it works.
• Window title. It would be nice if there was a Window.title property in the DSL. Instead, I've resorted to setting the title directly in my update function as a side-effect. Again, ugly but effective.

Are there better ways of handling these issues?

Originally the DSL only worked with classes that inherited from Control. We changed this a while ago to support text spans and other non control based Classed.

This might be possible now, feel free to take a closer look - would be a great addition :)

OK. I'm still learning the basics, but will try to take a look once I have a better grasp. Thank you.

Just wanted to let you know that I am working on this and hope to have a pull request ready soon. This will be my first significant contribution to an open source project, so please let me know if there's a particular protocol you'd like me to follow.

Nice! Taking a look at your PR right now!
