Replaces the misc/build.func bootstrap with the two-root core loader.
No other change: the engine contract (var_*, update_script, start,
build_container, description) is identical on both engines.
versitygw.sh additionally gains a trailing newline; it lacked one.
With this batch every ct/ script is on the core engine.
* Add twenty (ct)
* Apply suggestion from @tremor021
* Refactor backup and restore process in twenty.sh
Refactored backup and restore logic to use functions.
* Clean up blank lines in twenty.sh
Removed unnecessary blank lines in the script.
