dwm: parches restartsig, preserveonrestart, statuscmd-nosignal y swallow

Browse source 
- Mod+Shift+r reinicia dwm sin cerrar ventanas y cada una sigue en su tag
- Clics en la barra: red (nmtui), volumen (pavucontrol, silenciar, micro,
  rueda) y bluetooth (blueman, encender/apagar)
- swallow: lo que se abre desde st sustituye a la terminal
- Reglas: flotan centradas pavucontrol, blueman, nmtui y ventanas de Firefox

Subject: [PATCH] preserve clients on old tags when renewing dwm
By default, when dwm is recompiled-restarted all clients will
lose it's current tag and collapse to first tag. This patch preserves
clients on old tags, however note that layout order is not preserved.

Subject: [PATCH] Modifies quit to handle restarts and adds SIGHUP and SIGTERM
handlers.
Modified quit() to restart if it receives arg .i = 1
MOD+CTRL+SHIFT+Q was added to confid.def.h to do just that.
Signal handlers were handled for SIGHUP and SIGTERM.
If dwm receives these signals it calls quit() with
arg .i = to 1 or 0, respectively.
To restart dwm:
MOD+CTRL+SHIFT+Q
or
kill -HUP dwmpid
To quit dwm cleanly:
MOD+SHIFT+Q
or
kill -TERM dwmpid
