Couch Remote 1.0.5

Fixed the "Pair Selected" button in the setup window, which raised an internal error (an undefined reference) and never started pairing. The 1.0.4 command-parsing fix was not enough on its own because the graphical pairing path crashed before launching the pairing command.

Installable Python artifacts are attached. The Flatpak manifest is at packaging/flatpak/io.github.angelodelorenzo.couch-remote.yml.
