The blame view for a file is rather hard to understand and use

Two major issues:

• Blame UI doesn't include commit summaries and age next to commit hash
• There's no button to quickly load the blame view with the file of the commit preceding the one listed as the modifying commit for that line to look at what the file looked like before that commit

This can be observed by comparing these two views of the same file:

• Pagure: https://pagure.io/pagure/blame/setup.py?identifier=master
• GitHub: https://github.com/Pagure/pagure/blame/master/setup.py
