Wow, awesome work, but please, keep Pull Requests simple, it's preferable that you send 5-6 separate PRs, (one per feature/bug), so it's easier to review and merge.

I fixed what I needed locally and then decided that I should give it back to the community and pushed up my local changes.

I don't spend much time on Github and it would only let me submit a PR from the head of my master branch. I don't have time to break it out into individual branches so I figured that one bigger PR is better than not doing it at all.

Assuming that you have visibility into the individual commits, they are smaller and fairly self contained. It is likely to be easier to review each commit separately than to review the combined changes for the PR.
