Implement Han's VT102 bugfix (which works! wooot!).

Removed row_plaintext method (row_text is fine, the difference was (like in Perl's Term::VT102, row_text uses null bytes, and row_plaintext replaces them with spaces.. but there's no reason to even have the null byte method, right?).

Made VT102 screen dumps a config option. If VT102 screen dumps are off, we just get the NetHack output itself. This should help bugfixing. (I've already noticed a few anomalies like the @ not always disappearing when moving)
