feat(spaces): add force arg for moveWindowToSpace

Floating windows can be drawn over full screen windows so there should
be a way to move them into full screen spaces as well.

-/// hs.spaces.moveWindowToSpace(window, spaceID) -> true | nil, error
+/// hs.spaces.moveWindowToSpace(window, spaceID, force) -> true | nil, error
 /// Function
 /// Moves the window with the specified windowID to the space specified by spaceID.
 ///
 /// Parameters:
 ///  * `window`  - an integer specifying the ID of the window, or an `hs.window` object
 ///  * `spaceID` - an integer specifying the ID of the space
+///  * `force` - a boolean specifying whether the window should be tried to move even if the spaces aren't compatible
 ///
 /// Returns:
 ///  * true if the window was moved; otherwise nil and an error message.
 ///
 /// Notes:
-///  * a window can only be moved from a user space to another user space -- you cannot move the window of a full screen (or tiled) application to another space and you cannot move a window *to* the same space as a full screen application.
+///  * a window can only be moved from a user space to another user space -- you cannot move the window of a full screen (or tiled) application to another space. you also cannot move a window *to* the same space as a full screen application unless `force` is set to true and even then it works for floating windows only.
