nvim: continue fennel porting

Yeah I'm lazy but these are my dotfiles.
A quick summary:
* plugins.lsp.attach is now ported
* toast.core is reorganized
* new nil? and number? checks
* new assoc function
* new toast.table.unpack function (cross lua compat)
* toast.macros.tbl now uses assoc instead of from-pairs and group
* apparently I had forgotten to add {pre,post,init}.fnl before, so
  that's done now

Still todo: ftplugin, colors.
