bspwm: 0.9.10

# From 0.9.9 to 0.9.10

## Additions

- New node descriptor: `first_ancestor`.
- New node modifiers: `horizontal`, `vertical`.

## Changes

- The node descriptors `next` and `prev` might now return any node. The previous \ 
behavior can be emulated by appending `.!hidden.window`.
- The node descriptors `pointed`, `biggest` and `smallest` now return leaves (in \ 
particular `pointed` will now return the *id* of a pointed receptacle). The \ 
previous behavior can be emulated by appending `.window`.
- The *query* command now handles all the possible descriptor-free constraints \ 
(for example, `query -N -d .active` now works as expected).
- The rules can now match against the window's names (`WM_NAME`).
- The configuration script now receives an argument to indicate whether is was \ 
executed after a restart or not.
- The *intermediate consequences* passed to the external rules command are now \ 
in resolved form to avoid unwanted code execution.
