Entering '.' in profile "host" and/or "user" breaks restore

[DonEdwards]

For a single-user single-system environment, it makes sense to configure backintime profiles with dots in the "host" and "user" fields - skipping two levels of directories which, in this specific context, serve no function.

However, with this configuration, "restore" writes to /{profile]/{datetimestamp}/backup (copying the rest of the file path). "restore to" similarly writes to {wherever you tell it}/{profile}/{datetimestamp}/backup. {datetimestamp} in this referring to the snapshot being restored from.

Hi, thanks for your report! Your feature request is identical to #1304, and we're tracking that there. However, entering . in those path fields shouldn't be allowed at all, because it leads (as you encountered) to all sorts of unexpected breakage.

So it's best if we sanitize user input there, and I'm keeping this Issue open to remind us.
