New feature - collect and chart live data

[jxmot]

Create a configurable mode that will allow for the charting of live data.

Possible resulting issue(s):

• Repainting the chart might be noticeable when updating data
• The apex chart plug in may not be suitable for live data. Early tests with apex showed that adding data to a series while charting it will cause the scale to compress.

Possible implementations:

1. New data is applied to the chart in "clusters". For example, collect 1 hour(configurable) of data and then update the series.
2. Remove an equal quantity of series data points for those that are added. Should keep the scaling from occurring
3. TBD
