Support multiple usernames

[PanderMusubi]

Some people have multiple user names, one for work, a private one, one for a FOSS project, etc. Please support entering multiple users names, separated by commas. Merge all data for these users and report on the combined result.

Please list also the user names for which the report was generated and use the first user name as the one to report the result against, i.e. to do the personification.

This would alleviate the issue I am having where my data is 'split' because I changed my username.

Atm i have only one account but this behaviour would make sense if I did have more ;)

This sounds like a very sensible thing to do. Thumbs off for me!
