Changelog

• (New) Four new commands find, find-back, find-next, and find-prev are added to implement file finding. Two options anchorfind and findlen are added to customize the behavior of these commands.
• (New) A new quit command is added to the server protocol to quit the server.
• (New) A new $LF_LEVEL variable is added to show the nesting level.
• (Fix) Commands load and reload now work properly when the current directory is deleted. Also lf does not start in deleted directories anymore.
• (Fix) Server is now started as a detached process in windows so its lifetime is not tied to the command line window anymore.
• (Fix) Clients now try to reconnect to the server at startup with exponentially increasing intervals when they fail. This is to avoid connection failures due to server not being ready for the first client that automatically start the server.
• (Fix) The old index is now kept when the current selection is deleted.
• (Fix) Command shell-pipe now triggers load instead of reload.
• (Fix) Error messages are now more informative when lf fails to start due to either $HOME or $USER variables being empty or not set.
• Searching for the next/prev item is now based on the direction of the initial search.
