Fixes to Octave examples

- rename example modules from "example" to "swigexample", to avoid a
  warning from shadowing the Octave built-in function "example"
- remove deprecated "static" Makefile targets: there is no longer
  an option to build static Octave modules in the Examples Makefile
- emacs whitespace cleanup run on all files
