[Aavso-photometry] Chart id's

[Kate Hutton]

Wheww ... this system may be easier for the IT staff & I'm sure it is, but
the user/observer now lacks a basic & intuitive piece of information ... how
old is the chart I'm using?  Does not using the date as a chart identifier
uniquely determine the sequence?  Guess I don't really understand the reason
for this change.
