Bugfix: average temperature on arrival from RTE instead of display time This commit is heavily inspired by commits 05c770dc2911 and ecb71521d004. Reading the code, it was clear that a display time averaging process for measured temperature was implemented as was fixed for current depth display in the two mentioned commits. The bug for the late averaging of the temperature is, obviously, not as prominent as the current depth fault. The bug fixed here was nothing more than a visual glitch when first selecting the temperature display in the lower left corner (by default at the start of the dive, or by manually selecting it during the dive using the left button). So, to summarize. A small visual glitch fix, but more important, more consistent data handling and code. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
