dwm: gaps de 4px con atajos, audio con límite 100%, micro, bloqueo, capturas y clipmenu

- config.h regenerado desde config.def.h (faltaban los atajos de setgaps)
  e indentado con tabuladores
- gaps: Mod+-/Mod++ (teclado español) y Mod+Shift++ para quitarlos
- volumen limitado a 100% y refresco inmediato de slstatus
- silenciar micro con Mod+ñ y XF86AudioMicMute
- slock con Mod+Shift+l, clipmenu con Mod+v
- capturas con Impr (pantalla) y Shift+Impr (selección) usando maim
- quitar regla de Firefox que no hacía nada
- arreglar indentación de tile() tras el parche fullgaps
