[Helptags] add preview window to :Helptags command (#1357)

Browse Source 
+ In `fzf#vim#helptags`, we now also parse out the ex-command in the
  perl script so it's available for the preview (this is just an
  extra `\t(.*)` appended to the original regex).

+ Add the `--tag` placeholder to `:Helptags` with corresponding
  arguments.
