* adds a timer for Cold-FEg flasing to the IceT interface
* need to enter parameters for rate of dropping: slope and intercept
* adjusts the vacuum intensity according to
<pre>
objth['vacuum intensity'] = self.settings['cfeg_slope'] * diff.seconds + self.settings['cfeg_intercept']
</pre>
* use negative values for decreased intensity
* use original vacuum value for intercept
