Merge remote-tracking branch 'upstream/master'
Added the following options to databrowser:
- automatically refresh the history data (to avoid horizontal lines, when the live buffer fills up.
- allow to specify the future buffer, which is the time from now to the right side of the chart (the chart will only be scrolled when it reaches the border).
- Display the values at the cursor in the Properties table.
- Do not reset the trend appearance when the buffer size is changed.
Reverted one unnecessary change.
