New papers added to FLOSShub

I've uploaded metadata (and when available, actual papers) for some relevant 2015 open source conferences (including the 2015 OSS conference, HICSS, and Mining Software Repositories) to FLOSShub/biblio.

There are now 1589 papers on FLOSShub/biblio. It makes a nice addition/backup/source for Google Scholar and the other larger publishing sites.
