Code review comment for lp:~laney/ubuntu-archive-tools/generate-release-schedule

I've reviewed this code and it's all good, there's just one tiny bug that happens when the first release day is not last one of the month (as it is the groovy case), causing the first row to be repeated (so to be addressed for next cycles).

However, I've also added some changes to allow supporting events happening on days different from Thursday, such as the beta freeze.
