v0.20.0

Changes & fixes

• BREAKING: xplr shell (:!) will default to null (\0) delimited pipes, as
  opposed to newline (\n) delimited ones (i.e. will use Call0 instead of
  Call).
• Use new messages for safer file path handling (\0 delimited):
  • Call0
  • CallSilently0
  • BashExec0
  • BashExecSilently0
• Use new sub-commands for safer message passing:
  • -m FORMAT [ARGUMENT]... / --pipe-msg-in FORMAT [ARGUMENT]...
  • -M FORMAT [ARGUMENT]... / --print-msg-in FORMAT [ARGUMENT]...
    Where FORMAT is a YAML string that may contain %s, %q and %%
    placeholders and ARGUMENT is the value per placeholder. See init.lua.
• Following hooks can be defined in the config files using an optional
  return { on_* = { list, of, messages }, ... } statement at the end.
  • on_load
  • on_focus_change
  • on_directory_change
• Use --vroot to isolate navigation of an xplr session inside a specific
  directory. Interaction still requires passing full path, and shell,
  lua functions etc still can access paths outside vroot.
• Use the following messages to switch vroot at runtime, or the use key
  bindings available in the new builtin mode "vroot" (mapped to : v).
  • SetVroot
  • UnsetVroot
  • ToggleVroot
  • ResetVroot
• Use $XPLR_INITIAL_PWD and Lua equivalent to implement workspace like
  features without using virtual root. Use keys gi to go to the initial
  working directory from anywhere.
• Use the convenient xplr.util utility functions in your Lua function calls.
  See xplr.util API docs.
• Improved CLI errors.
• Finished documentation (finally).
• UI updates to handle newlines in path.

Thanks to @jmcantrell for reporting and help implement fix for the critical newline-in-pathname bug.
