the problem here was that in the initial case the function got the
previous state of the tree wrong, so the insertion of a second client
ended up in a unpossible state of the tree, this should not happen
anymore now.
The insertion is now also way more stable, since in a errorcase the
client is not just not placed in the tree but associated with a window
tree, its just not placing the client in the window tree at all.
If someone starts to drag a client arround, then the client will shrink
into a icon, that now is always at the position of the mouse cursor, if
the drag ends, the client will be placed in the client currently below
it. The client will be placed in a place where the mouse cursor was
currently closer to.
Summary:
This implements the possibility to "break out" a node in the tree which
means that the node will be appended or prependen to the parent in the
grandparent.
The other function "joins" the node to the node before or after.
Basically it will be added as a child, and if necessarry the client
of this node will be added in a new Window Tree and also added as a child.
With the new actions you can move the focused window right/left/up/down
with keybindings.
If the window will "break out" or "join" depends on the parent split type.
Sample:
1|4|6
2|4|6
3|5|6
(Same Number means same Window)
1 is focused.
Left Key is pressed.
1 is in a vertical split so the window will "break out".
Result:
2|1|4|6
2|1|5|6
Now another key:
Down Key is pressed.
1 is in a vertical split so the window will "join".
Result:
1|2|4|6
3 3|5|6
