I agree, that part is a mess. Hopefully we wont have this degree of
churn in this area again, but I do wish that we had more block consumers
based off the block tree. Having cross-dependent stuff in different
trees just gets messy quickly. Thanks for resolving it though, the IDE
code wasn't pulled in when I sent the pull request or I would've done it
myself. I usually try to make sure that it merges cleanly with your head
of tree before sending it out.

That's for the patches that I pulled from his git tree. It should list
him as committer too.
