A remote machine's folders can be walked from the new-chat window, and a long answer no longer rewrites the saved conversation every few seconds as it streams.

Changes:
• Browse on a remote server opens a folder browser: a path you can click back along, up and back buttons, a filter that narrows as you type, places to jump to (home, the root, your starred and recent folders, your projects), a star on any folder, and a note of how many chats already work in each.
• It remembers where you were on each server, Ctrl+S hops to another machine without leaving, Ctrl+B stars the folder you are in, and Ctrl+Enter starts the chat there. It works from the keyboard alone: arrows or Ctrl+N and Ctrl+P to move, Enter to open a folder, Alt+Up and Alt+Left to go up and back, Tab to complete.

Fixes:
• A long answer used to rewrite the whole saved conversation every five seconds while it streamed, which could add up to more than a gigabyte a day. It is now written once per half minute, and not at all when nothing changed.
