revisions change log for display

[anthonylindsay]

Further to chats on slack, I whipped up a POC for a view to display the edit revision log messages as a block, which can be displayed on a node.
Attaching config here for starters as am not sure what the proper procedure is.
NB I have appended .txt to the filename as github appears to hate yml files.

views.view.revision_log.yml.txt
