Update for use with -batch switch

Browse source 
- Require the `package' and `help-fns' libraries which aren't loaded
  when using the `-batch' switch with Emacs.

- Add options to specify which style sheet to use and whether to only
  print the body (so no `<doctype>' or `<html>' etc.)

- Reverse the list of symbols to show up in the same order as they
  appear in the buffer.

- Replace `case' with a `cond', I didn't realize `case' was part of the
  cl-lib.

- Add function to be used with the `-batch' switch.
