Releasing Table Mode v3.1

* Removed table border and related options. You can now optionally have
  a header instead, simply add a table header and add a border to it
  triggered by the vim iabbrev '+-' on the line immidiately after the
  header and it will expand to the correct border. It will auto update
  as the table realigns with changes. Similar approach as followed by
  tables in org-mode.
* Fixed bug of incorrect indentation of a newly added formula line.
* Fixed bug in ConvertDelimiterToSeparator causing incorrect
  tableization of commented blocks of delimited content.
