Instrument Panel Improvement

Instrument panel allow to select multiple gauges by pressing the Ctrl + Left Click or using a rubberband.
The location and size of all selected gauges can be adjusted in a single step.
Copy and paste of the selected gauges is supported.
The layout grid is removed. Now the borders of the gauges act as magnetic lines making it easy to align/adjust gauges.
If multiple gauges are selected, the arrow keys can be used to move the gauges by pixel (without snapping to the magnetic lines). Additionally, the arrow keys can be used with Shift to align all gauges to the top, left, bottom or right border, together with Ctrl the size can be adjusted (Ctrl+Right Arrow, Ctrl+Down Arrow) or aligned and sized (Ctrl+Left Arrow, Ctrl+Up Arrow).
