Bundle curated community plugins (2.1.8-4)

Vendored from upstream, pinned by commit (see debian/extra/README.source):
- gitstatus, gitopen, fontconfig, open_ext, select_colorscheme,
  smoothcaret, nerdicons (font mapping patched to DATADIR, Ships the
  Symbols Nerd Font Mono TTF, SIL OFL 1.1)
- lite-xl-lsp (complete LSP client; idle until a language server is
  configured) plus the lite-xl-widgets library it requires
- 104 language syntax plugins (none duplicate the nine bundled in core)

settings GUI left out upstream is broken: it requires a
libraries.widget.fonts widget that does not exist in
lite-xl-widgets at any revision.
