Update bStats Metrics and add wrapper class for new graphs (#3451)

This PR updates the version of the bStats Metrics class to the latest version, supporting plugin IDs in place of just plugin names. It also adds the following graphs:
- Active permissions backend
- Active economy backend
- Whether or not a command has been used as a bar chart (pending bStats backend implementation)
- Version history graph as a multiline graph (also pending bStats impl)

It also removes the weird `getMetrics` and `setMetrics` APIs which should never have been API in the first place.
