Full Floating System + Scratchpad

[BarutSRB]

Added a first class floating system, you can float unfloat windows, when a window is unfloated it will get tiled back, to reveal floated windows use "Raise All Floating Windows" command. When you assign a window to a scratch pad it gets hidden right away and you need to use "Toggle Scratchpad Window" to show/hide it (it will remember its size and position before hiding). You can have only one window assigned to the scratchpad, and you must unassign or close it first before you can assign another window to the scratchpad.

The release with this and many other things will be released probably tomorrow.

Would be cool if the window currently in the scratchpad could show in the bar somehow.

Float management is a big win 👏

Is it possible to specify a window as a scratchpad directly within a window rule?

Also, it would be incredibly helpful to have an API command to turn a specific window into a scratchpad using its window ID. From what I can see, the current API only allows you to toggle the currently focused window.
