gain change buttons on xNodes

[Geoff Fairbairn]

ver. 1.2.0m (build Mon Jul 29 12:42:28 EDT 2013)

Having trouble with the gain adjustment buttons on the 'Meters' page. The amount that they increment/decrement the gain by is usually 2dB (for the bigger buttons, 0.2dB for the smaller ones) or more - sometimes much more, and often they don't increment/decrement the gain at all.

I just clicked a small button and the gain changed from -4.8 to -5.9.

They're a great idea but they're unusable which is a pity as they would be more convenient that the settings in the 'Sources' and 'Destinations' pages.
