Add charging indicator and pacman package, bump to 1.1.0

- Show charge/discharge power in watts, a battery graphic with charge
  bolt, a power history graph and the estimated time until full or
  remaining (respecting the 80 % charge limit) in the app, the panel
  widget, its tooltip and `predatorctl status`
- Add packaging/arch/PKGBUILD that builds a pacman package; the kernel
  module ships as DKMS source and is rebuilt for every kernel
- Bump version to 1.1.0
