#301 Window hints are not set correctly

[QW3RY]

yad doesn't set the window type to DIALOG by default (xprop gives _NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_NORMAL instead of _NET_WM_WINDOW_TYPE_DIALOG). The --splash option works fine (xprop gives _NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_SPLASH).

This wrong window type causes some window managers (in my case i3 to treat a yad dialog as normal window and thus rendering it as a normal "tile" (see screenshot).
