   * plus ".column." plus the logical name of your column. 
   * <p>
   * For example, if you are creating a column named "quality" in the table 
   * TABLE_TORRENT_FILES, youwould have to add the following to your language 
   * file:<br>
   *    <code>Files.column.quality=<i>Column Title</i></code><br>
   * and if you wish to have a short description of the column (visible when
   * the user is setting up columns), create another entry with the same key
