Allows the user to disable the window dragging

[Anapher]

I hate it when the user can move the window with a grid at the window. This property allows me to disable that.

@alkalinee you also disable the left mouse double click action and right click system menu action...

@punker76 Okay, I improved the code a bit so only the MouseDown-event doesn't get subscribed. I think it's fine so, because there would be no titlebar anyway for the double click event (the system menu is available)

I can't see a use case for this request, and even if, I think it's too special to add it to MetroWindow.

Besides my objection, I see two more issues:

• The property should be called CanWindowDragMove or IsWindowDraggable or so
• The implementation does not support changing the value at runtime.

@thoemmi Hi, I think it's very important that you can disable the dragging, if you don't have a titlebar. It just sucks to write an own titlebar and the user can drag the window from every position. Okay, naming was not my best, can be improved :). Why would you change this at runtime? But it would be really easy to make that changeable, if that's the reason.

I think: More control for the programmer = better

[thoemmi]

OK, I see your point. I wasn't aware that you want to disable dragging the window by clicking anywhere inside the window. I even second that :-) And you're right, there's no need to change it at runtime.

Concerning the naming: it is a flag, which switches something on or off, and as such the naming should reflect that.

Okay, i changed the name.

@thoemmi the IsWindowDraggable can now be changed at runtime 4f40742
