Undelete charts with all objects. Feature has 2 uses as in MT4: a) to restore deleted charts and b) to duplicate charts for MTF analysis

As in MT4, the undelete function is useful for restoring charts that had been accidentally deleted. Undeleting the same chart multiple times also gives one the ability to view the same objects of the chart across different time frames, as undeleting the chat multiple times essentially duplicates the chart with its objects multiple times so that different TF can be applied to each of the duplicates for MTF analysis
