bspwm: Update to 0.9.9

# From 0.9.8 to 0.9.9

- Fix a memory allocation bug in the implementation of `wm --restart`.
- Honor `single_monocle` when the `hidden` flag is toggled.

# From 0.9.7 to 0.9.8

- Fix a potential infinite loop.
- Fix two bugs having to do with `single_monocle`.
- Honor `removal_adjustment` for the spiral automatic insertion scheme.

# From 0.9.6 to 0.9.7

This release fixes a bug in the behavior of `single_monocle`.

# From 0.9.4 to 0.9.6

## Additions

- New *wm* command: `--restart`. It was already possible to restart `bspwm` without loosing the current state through `--{dump,load}-state`, but this command will also keep the existing subscribers intact.
- New settings: `automatic_scheme`, `removal_adjustment`. The automatic insertion mode now provides three ways of inserting a new node: `spiral`, `longest_side` (the default) and `alternate`. Those schemes are described in the README.
- New settings: `ignore_ewmh_struts`, `presel_feedback`, `{top,right,bottom,left}_monocle_padding`.
- New node descriptor: `smallest`.
- New desktop modifier: `active`.

## Changes

- The `focused` and `active` modifiers now mean the same thing across every object.
- Fullscreen windows are no longer sent to the `above` layer. Within the same layer, fullscreen windows are now above floating windows. If you want a floating window to be above a fullscreen window, you'll need to rely on layers.
- Pseudo-tiled windows now shrink automatically.

## Removals

- The `paddingless_monocle` setting was removed (and subsumed). The effect of `paddingless_monocle` can now be achieved with:
```shell
for side in top right bottom left; do
	bspc config ${side}_monocle_padding -$(bspc config ${side}_padding)
done
```

# From 0.9.3 to 0.9.4

## Changes

- The following events: `node_{manage,unmanage}` are now `node_{add,remove}`.

## Additions

- New monitor/desktop/node descriptors: `any`, `newest`.
- New node flag: `marked`.
- New monitor descriptor: `pointed`.
- New *wm* command: `--reorder-monitors`.
- Receptacles are now described in the manual.
- New `--follow` option added to `node -{m,d,n,s}` and `desktop -{m,s}`.
- The *subscribe* command now has the following options: `--fifo`, `--count`.
- New settings: `ignore_ewmh_fullscreen`, `mapping_events_count`.

# From 0.9.2 to 0.9.3

## Changes

- *click_to_focus* is now a button name. Specifying a boolean is deprecated but will still work (`true` is equivalent to `button1`).

## Additions

- `node -r` now accepts a relative fraction argument.
- An option was added to `query -{M,D,N}` in order to output names instead of IDs: `--names`.
- New rule consequence: `rectangle=WxH+X+Y`.
- New settings: `swallow_first_click` and `directional_focus_tightness`.
