feature request : Show Printing History

[korneel 176]

Daid and other;

the main reason I love to use OctoPrint over the default interface is that one of the things it does is keep track of whatever I printed.

I recently had to do a lot of printing with a lot of printers so had to use the interface again and it has certainly improved over the past 6 months!

there is still one thing that i would love to have;

can we have a history of whatever was printed? perhaps even a status that says "done printing X" after the print is done so at least i know the filename of what has been printed..

that would help me prep a SD card and so i would know what has been printed and what has not..
