Measure missing tooltip for sensors sample recording interval

[quozl]

There is no tooltip or text explaining the sample recording interval widget.

Measure-30, XO-1 os301, XO-1.5 os206.

With 0.88, there is a tooltip:

if hasattr(self._loginterval_combo, "set_tooltip_text"):

self._loginterval_combo.set_tooltip_text(_('Sampling interval'))

That code is in the Sound toolbar, but I was talking about the Sensors toolbar. Here's the patch I propose as solution for this ticket.

Missed this one. It will be included in v32 at what point that is released.
