WITHDRAWN: replace current VU meter with a three-colored VU meter in main window (@ e8554ea )

[FulopNandor]

The current single-colored (red) VU meter (member variable vuOutput belonging to the class VuMeter) is replaced with a green-yellow-red colored VU meter (member variable m_vuMeterMain belonging to a new class vuMeterMain) on the main window of Dexed.

The new VU meter contains 6 yellow and 6 red blocks (“LEDs”); the maximum absolute float output value of the plugin, 1.0F, is adjusted to the border of the last yellow and first red block.

Please note that only the view of the VU meter has been changed in this commit, its scaling has not been adjusted yet, so the scale is still not based on dB units.
