Make all windows moveable by default

[Dmitry Timoshkov]

Hello,

an app I'm working on creates a top level window without a caption,
and returns HTCAPTION on WM_NCHITTEST to make the window moveable by
dragging its client area. The app's window currently is not moveable
under Wine because we don't set MWM_FUNC_MOVE WM hint for captionless
windows. This patch makes my app's main window moveable.

Changelog:
    Make all windows moveable by default.
