Add (e)RPM black box field (#640)

* Add RPM black box field

* Add RPM to example graphs

* Use same scaling for all RPM fields

* Change name of RPM field to eRPM(/100)
 - Add RPM to enabled/disabled black box fields in header dialog
 - Add escapeRegExp function to tools.js
 - Escape nameRoot before using as regexp for creating [all] fields in graph_config
