Add a syntax table to dwarf-mode.el

This adds a syntax table for dwarf-mode to dwarf-mode.el.  I noticed
the need for this when trying to use mark-sexp (C-M-SPC) on a hex
number -- it copied the trailing ">" as well, which isn't desirable.

I've also bumped the version number to make this simpler to install
via the Emacs package system.

Tested locally.  I'm checking this in.
