The "I did way too much hacking at WordCamp" release :)

Note: graph data from earlier versions will be rendered incorrectly in this version. But legacy data should roll-over after 24 hours.

This release includes:

• Make graph data easier to understand
• Add more useful metrics to the graph
• Fix version check for MariaDB < 10.2
• Drop plugin's tables on uninstall
• Use SAVEQUERIES data if exists
