[migration] move 'entities' table changes from 3.19.0 to bootstrap script The 'mtime' and 'source' columns need to go away before we attempt to do anything else with the repo, otherwise any addition of an entity is going to explode.

 * @description Create a sortable table with multi-column sorting capabilitys
 *
 * @example $('table').tablesorter();
 * @desc Create a simple tablesorter interface.
 *
 * @example $('table').tablesorter({ sortList:[[0,0],[1,0]] });
 * @desc Create a tablesorter interface and sort on the first and secound column column headers.
 *
 * @example $('table').tablesorter({ headers: { 0: { sorter: false}, 1: {sorter: false} } });
 *
 * @desc Create a tablesorter interface and disableing the first and second  column headers.
 *
 *
 * @example $('table').tablesorter({ headers: { 0: {sorter:"integer"}, 1: {sorter:"currency"} } });

 *
 * @param Object
 *            settings An object literal containing key/value pairs to provide
 *            optional settings.
 *
 *
 * @option String cssHeader (optional) A string of the class name to be appended
 *         to sortable tr elements in the thead of the table. Default value:
 *         "header"
 *
 * @option String cssAsc (optional) A string of the class name to be appended to
 *         sortable tr elements in the thead on a ascending sort. Default value:
 *         "headerSortUp"
 *
 * @option String cssDesc (optional) A string of the class name to be appended

 *
 * @option String sortInitialOrder (optional) A string of the inital sorting
 *         order can be asc or desc. Default value: "asc"
 *
 * @option String sortMultisortKey (optional) A string of the multi-column sort
 *         key. Default value: "shiftKey"
 *
 * @option String textExtraction (optional) A string of the text-extraction
 *         method to use. For complex html structures inside td cell set this
 *         option to "complex", on large tables the complex option can be slow.

 *         prepended to user-selected rules. Default value: null
 *
 * @option Boolean sortLocaleCompare (optional) Boolean flag indicating whatever
 *         to use String.localeCampare method or not. Default set to true.
 *
 *
 * @option Array sortAppend (optional) An array containing forced sorting rules.
 *         This option let's you specify a default sorting rule, which is
 *         appended to user-selected rules. Default value: null
 *
 * @option Boolean widthFixed (optional) Boolean flag indicating if tablesorter
 *         should apply fixed widths to the table columns. This is usefull when
 *         using the pager companion plugin. This options requires the dimension
 *         jquery plugin. Default value: false
 *
 * @option Boolean cancelSelection (optional) Boolean flag indicating if
 *         tablesorter should cancel selection of the table headers text.
 *         Default value: true
 *
 * @option Boolean debug (optional) Boolean flag indicating if tablesorter
 *         should display debuging information usefull for development.
