whid script calls undefined updatePanel

[kainonergon]

undefined updatePanel causes errors in whid.

• With whid last one hidden window is restored, but the rest of hidden windows are lost. See https://forum.manjaro.org/t/whid-from-bspwm-scripts-looses-hidden-windows/41085
  EDIT. This one is solved if in line 65 change sed -i "${lineNumber}d" to sed -i "${lines}d"
• With whid hide notify-send doesn't work because of it.
