[x2go-i18n] Suggestions

[Daniel Lindgren]

As Terje is proposing, the error code wouldn't *just* be a number, it
would also contain an identification string of some sort.

One example is STOP-codes in Windows, it's easy to find
troubleshooting info about "STOP 0x0000007B", a localized error
message - something like "Åtkomst till startenhet misslyckades" -
wouldn't return much when Googling for support.

Cheers,
Daniel
