Remove Gwydion gd-bugs maintainership notice; That's long gone
Add some page break headers
Small fixes to leverage more builtin Emacs

* Remove most of the custom Dylan reindent line functions

* Remove dylan-mark-function; the Emacs work works using
beginning-of-defun and end-of-defun. Remove the bindings for these since
the default Emacs bindings should work.

* Hoist syntax table out of the mode function

* Remove the bindings of ; , > \n \t. Users who want this kind of
behavior can bind the key themselves to
reindent-then-newline-and-indent.

Fixes #5, #6 and #7.
