* Fix: Do not swallow traces when crashing before log init (e.g.
during argument parsing)
* Show a link to the troubleshooting page, when an error happens
* (Formatting done by autopep8 in pmb/config/init.py)
Previously, if you passed something like ~/build to the init function
for work directory, it would create a directory, .\~/ in the current
working directory instead of resolving ~/ to the user's home directory.
This allow allows using ../ to specify a path.
The `cli.ask` command would forcibly lowercase the whole string. This
made the script unusable on a non-FHS-compliant system, like mine, where
the users's directories are under `/Users/`.
