Feature Request: historical graph for ups stats

[ivanjx]

i would like to see historical graph for ups stats such as: ups load, battery charge, ups power, input voltage, etc. i think keeping them for 30 days should be good enough but it would be better to be able to customize this.

I would add that it would be helpful to keep a record of events, i.e. UPS on battery, shutdown, etc.
