Add animation for special windows

[ErfanRasti]

We have a great separate animation for special workspaces like this:

animation = workspaces, 1, 1.94, almostLinear, slide
animation = workspacesIn, 1, 1.21, almostLinear, slide
animation = workspacesOut, 1, 1.94, almostLinear, slide
animation = specialWorkspace, 1, 1.94, almostLinear, slidefadevert
animation = specialWorkspaceIn, 1, 1.21, almostLinear, slidefadevert
animation = specialWorkspaceOut, 1, 1.94, almostLinear, slidefadevert

But there is no such thing for special windows. I mean, it should be separate animations for special windows in and out (Animations for moving windows to or from special workspaces), like this:

# These are implemented perfectly
animation = windows, 1, 4.79, easeOutQuint
animation = windowsIn, 1, 4.1, easeOutQuint, popin 87%
animation = windowsOut, 1, 1.49, linear, popin 87%

# These aren't implemented
animation = specialWindows, 1, 4.79, easeOutQuint
animation = specialWindowsIn, 1, 4.1, easeOutQuint, popin 87%
animation = specialWindowsOut, 1, 1.49, linear, popin 87%

I think it can be implemented easily. The animation tree can be in this format:

 ↳ windows - styles: slide, popin, gnomed
    ↳ windowsIn - window open - styles: same as windows
    ↳ windowsOut - window close - styles: same as windows
    ↳ windowsMove - everything in between, moving, dragging, resizing.
    ↳ specialWindows - styles: same as windows
      ↳ specialWindowsIn - styles: same as windows
      ↳ specialWindowsOut - styles: same as windows
