Add capability to append data to Exodus files.

* Rename/make public:
  ExodusII_IO_Helper::_created -> ExodusII_IO_Helper::opened_for_writing
  ExodusII_IO_Helper::_opened -> ExodusII_IO_Helper::opened_for_reading
  ExodusII_IO_Helper::_verbose -> ExodusII_IO_Helper::verbose

* Adding append() setter/getter to ExodusII_IO and Nemesis_IO objects.
  If the _append flag is set, open file for writing in the
  write_nodal_data() function rather than creating it.

* Adding read_only flag to ExodusII_IO_Helper::open(), so we can also
  use this function to open files for writing.

* Print a warning if the append flag is set and the user calls
  ExodusII_IO::write(), as this function is not actually capable
  of appending anything...

* Fix up/add some documentation.
Improve error message when trying to write mixed element meshes with Exodus.

Also, use an actual if-test rather than an assert to avoid dying with a segfault in opt mode.
Adding current_filename and sanity checks to ExodusII_IO.
Factor out common code from the write_nodal_data and
write_nodal_data_discontinuous functions.
