/** Draws the column 2 (AutoUpdate) of ScriptRepositoryView.
*
* This function is called every time the ScriptRepository needs to
*draw the widget for the AutoUpdate of the file/folder inside the
*ScriptRepository. Instead of displaying the strings 'true' and
*'false' it will draw a checkbox that 'hoppefully' will better
*indicate to the user the condition of the entry as well as
*encourage him to act. The action will be dealt with at the
*editorEvent.
*
* When this method is called, it will get the index in order to
*retrieve the information about the state of the entry
*(folder/file).
*
*
* @param painter: Required to draw the widget
* @param option: Provided by the framework and has information
*displaying the widget.
* @param index: Identifies the entry inside the RepoModel
* (indirectly the file / folder).
