Subject: [PATCH] Improve help and screen recording keybindings in sway

This commit shuffles around some sway keybindings and improves the
screen recording experience by adding a small wrapper around `slurp` and
`wf-recorder` conveniently called `record-screen`.

* `$mod+F5` now reload the sway configuration,
* `$mod+Ctrl+r` starts a screen recording (to stop it, go to workspace 7
  and kill the process),
* `record-screen` and the firefox sharing indicator are both on
  workspace 7 now, making it the "trash" workspace,
* `$mod+F1` and `$mod+Shift+h` now open Firefox with the docs of our
repository availabe under `help.local`.
* To not infuriate `qMasterPassword` users, that is now available under
`$mod+Shift+m` instead of `$mod+F1`.
