Add 0.10.1 release notes to docs and minor tool updates. These were little fixes I found out while doing the 0.10.1 release, might as well have them all in trunk so we don't have to repeat the process when 0.11 goes out. There are still a few bzr-specific things lingering we need to clean up, but not tonight (most of the toolchain is now git-aware).

Open 0.10.2 branch for development. I don't expect to see much happen in this branch, but we'll have it available so people can contribute bug fixes and make pull requests. If we get enough contributions here, eventually we'll put a 0.10.2 release out.

Releasing version 0.10.1. A few last-minute fixes in various places for docs to build and full test suite to pass, as well as documenting the release in the docs.

Updated docstrings, following the convention in kernelmanager.py.

Lowercased format argument to image_tag

Applied lowercase_with_underscores naming convention

tweaked close dialog and added prompts to prevent silent remote close

Merge branch 'master' into trunk

Uncommenting reply_socket.recvmore that was broken in 2.0.7.

Stop-gap fix for crash with unicode input. The fix is highly suboptimal, as we're still ignoring unicode input. But at least we don't flat out crash, until I can work on it tomorrow.
