[Feature]: VT100 emulation

[TheEndOfTheRiver]

Problem statement

Looking for support for VT100 emulation.
I play and admin for Shattered Kingdoms

As I saw that you were actively developing a client and asking for feedback, I thought this was a moment for me to speak up.

Proposed solution

Here is a page that lists VT100 emulation as a feature for mud clients. It is a commonly advertised feature. It apparently is not difficult to support. I found MS documentation for the protocol.

Current behavior is: on terminal-type negotiation, QMud answers second TTYPE SEND with "ANSI", not "VT100", and on the MTTS response it sends MTTS 13 (UTF-8) or MTTS 9 (non-UTF8), which sets ANSI/UTF-8/256-color bits but not the VT100 bit.

Rendering-wise, the ANSI parser in runtime handles CSI SGR (...m) styling/color codes, but not general VT100 control sequences like cursor movement. So not full VT100 emulation.

I will implement full VT100 support exposed via a toggle next to the TTYPE field in world properties.
