Florian Müllner c8c93b2a70 extensions-tool: Implement enable/disable commands
This replicates the most basic functionality of the existing
gnome-shell-extension-tool, albeit using a git/gio/gsettings
style command interface rather than plain options; this will
allow us to implement more complex commands that have options
on their own in the future.
