Latest update - table code

Due to popular demand I've taken the jquery.tablesorter.pager plugin and modified it:

• to handle paging better ("button links");
• adding pagination size options;
• apply simple (table wide) filtering;
• added functionality to export the current table contents as excel, csv, tab, json ... format;

All these are driven by additional classes on the table:

• "filter" - add a simple text filter;
• "paginate_.._.._.._.." where the ".." are replaced by the number of rows to display (or "all")
  To note which entry you wish as default prefix it with "x" e.g.
  paginage_10_x25_50_all gives you 4 options, 10 per page, 25 per page, 50 per page and "all" and sets the default to 25;
• "export_.._.._.._.." where ".." are replaced by formats currently (json, txt, csv & xls)
  e.g.
  export_txt_csv_xls
