New Metrics for MTB - Bike Carrying Time/Elevation Gain

... 2 new metrics (estimates) mainly relevant for MTB or Race bike steep
passes
... a) Time Carrying = moving < 8kph, gaining height, no power, no
cadence
... b) Elevation Gain carring = same criteria, but adding up the
elevation gain

Since there is a certain level of error, the metrics is named as "Est".

AllPlot - Smoothing also for "Left Border"

Problem:
... data points of "Smoothing" settings are set to Zero in result
... this cause e.g. Zero Altitude Values when Plot Smoothing is active
Solution:
... also most left values are "smoothed" now (using only the datapoint
left of them to create the average)
