Archive some old CCC Schedule related apps (found using app-match.R)
In addition to the 33C3 Fahrplan removal requested and discussed here #1370 (closed) there are some CCC related apps which are even older.
(the pdf file allows to cut and paste the application ID if that should be needed) am_heatmap_info.metadude.android.congress.schedule.4.pdf
Probably Timeriffic (updated January 2011) is a candidate for the archive too.
I updated some minutes ago so that apps which have got no update in f-droid within 5 years or where added to the archive more than one year ago and then never got an update stick out more visibly.
The plots were generated with ./app_match.R -v 2 -m 0xff --mtime updated
.
In addition to flagging archival candidates the plots can help to find more up-to-date alternatives, but as there are more than 100 plots that would match the 5 year criterium I'm unsure how to proceed.
