Add arrow left/right, /w alias, auto /msg on Tab in window 1

- Arrow left/right to move cursor in input (UTF-8 aware)
- /w as alias for /msg
- Tab on window 1 with empty input auto-inserts /msg <nick>
- Tab after /msg completes from PM nick list
- Improved Swedish word filter (ASCII-only + UTF-8 variants)
