Moved zoom control to below sectorgrid to allow more space for long range scanner controls.

Inspection Label and Button are now relative to sectorgrid center.
Added controls and powerbars for Long Range Scanners.

System power management is still a placeholder.
Added Long Range Scanner logic to server and client.
Scanning now effects Sensor Range.
Avoid Scanner GUI updates while in 'Inspect' mode (GUI elements won't exist).
