================

New features:
- Adjustable window list width
- Recognition of terminal control sequence input, enabling use of arrow keys and Ins/Del/Home/End/PgUp/PgDn
- Chat logging

Bugfixes:
- Unhandled network read error on RST
- Unhandled network write errors on blocking and RST
- Race condition and unportability in signal handling (textbook case for djb self-pipe trick)
- Unhandled EINTR on resize during terminal write (planting Python firmly in the "Worse is Better" camp)
- Neglected terminal escaping for topic and status strings

Removed antifeatures:
- Microsoftesque redirection of crash tracebacks to debug.log

Performance:
- Lookup tables for character escaping and casefolding
- Full buffering of screen updates

Behavior changes:
- Key mapping for prompt to scrollback focus switch (not presently very useful) changed to Ins, freeing Tab for future completion feature
- C-x and Esc states now cancelled by C-g rather than repeating the original; Esc must always start a new escape sequence for terminal controls not to leak
- chdir to yrc home on startup to simplify config and log access

Documentation:
- Flesh out stub manual section on configuration and now logging
- Key mapping updates and typo fix

- Active window indicator changed from > to * for consistency with tmux
- "Return" keybinding removed from scrollback window as it would be prone to accidental message posting
- Reconnection bugs fixed
