Download mods for both sides with --side both (fixes #14)

* Add option to automatically close after a user-specific amount of time

Add the -t/--timeout command line option to specific a number of seconds to
wait before automatically closing if there is no update or user-interactivity
required.

* Also use timeout setting when prompting about optional mods after/during an update

Additionally, clears the TODO comment.

* Change default timeout to 10 seconds
