cagebreak: 1.5.0 -> 1.6.0

Fixes issues:
- 24:
  > Cagebreak up to and including release 1.5.1 had an error, where the code
  > incremented a variable and not a pointer. This resulted in a bug in a
  > surface counting iterator.

- 25:
  > Cagebreak, beginning with release 1.5.0, when a keybinding containing an
  > output configuration is removed from the list of active keybindings, the
  > output configuration contained in this keybinding is destroyed in order to
  > prevent memory leaks. However, after an output configuration was applied,
  > it was inserted into the list of active output configurations and if it was
  > later destroyed, this led to a use-after-free memory corruption.
  >
  > Starting from release 1.6.0, output configurations are copied before being
  > inserted into the list of active output configurations and therefore remain
  > valid even if the original is freed.
