mIRC formatting

Orbit renders and lets you compose classic IRC formatting. Use the composer's toolbar (B / I / underline / colour), or the keyboard:

Style Key Code
Bold Ctrl/Cmd+B \x02
Italic Ctrl/Cmd+I \x1D
Underline Ctrl/Cmd+U \x1F
Strikethrough \x1E
Monospace \x11
Colour toolbar \x03FF,BB
Hex colour toolbar \x04RRGGBB
Reset \x0F

Colours use the 99-entry mIRC palette (\x03 followed by a 1–2 digit foreground, optionally ,background). Orbit's composer writes these codes for you; incoming messages from any client are rendered with full colour and styling.

Formatting is "sticky" — turn on bold and it stays on for the next message, exactly like classic clients.
