There is an essential command when developing a new parser with bovine that is bovinate, this gives all the
buffer information about the tags and helps the developer understand what information is been change.

The idea of this patch is simple, provide a major mode for the bovinate buffer base on the emacs-lisp mode,
giving that there are a few similarities in the output, it also add more information in the buffer name, so
you can have different output buffers at the same time with different names.

The idea  in the future is to add more information in the bovinate buffer, so it can truly serve as a debugger
information buffer.

There is 2 patch attached, one of them is the change of the function and adding of the major mode, the other one
adds the display behavior, so it can also be automatically displayed.
