The GUI, the bad and the ugly

So this is hopefully the last release candidate before RTM.

Usually, at this stage, we wouldn't add new features, but restic 0.17 made a killer feature that was quite easy to implement.
The feature allows to run commands and backup their stdout, while getting the error codes from said command (I look at you mysqldump !)
It has been implemented as backup_opts.source_type: stdin_from_command and backup_opts.stdin_from_command: your command parameters in the config file.

Another minor feature is --housekeeping CLI parameter which is just a quick shorthand for existing code.
Finally, and since we have housekeeping, a new task creation entry was necessary, in order to fully appreciate it ;)

As usual for the last RCs, CLI didn't really need a lot of love (it's used for more than 100 workloads), but GUI did.
Getting the GUI right si really a painfull experience, but the payout is enough when it comes to quickly write config files that later can be used on headless servers.

Anyway, here's the full list of changes since RC3
