As of 0.10.0, Bitcoin.org began serving a torrent of all the release files. Because the torrent uses web seeding, it had to have the same name as the directory holding the files, which was 0.10.0. @laanwj requested a more descriptive name in https://github.com/bitcoin/bitcoin.org/issues/748, so we renamed all the directories to bitcoin-core-VERSION and created redirects for old links.
This commit updates the 0.10.1 release notes and release process documentation to use the bitcoin-core-VERSION directory natively from now on. I also updated some other Bitcoin.org-related information in the release process to describe our current process.
Please let me know if you need a separate PR to update the release process in master so these steps don't get forgotten.
