Implemented Long Range Scanning

Upgraded the Sensor System to provide a longer range scan that is 8 times further than the static sensor range.  The scan is transient and requires the Sensor system to be fully charged. Currently, the results of the scan will appear on all Systems using the sectorgrid (though this can be changed).

New Sensor GUI:

Let me know if the charge rate or scan range should be changed. I can also distribute the updated "Zoom Controls" to all other systems using the sectorgrid. Issue #46 also has some other ideas for Sensor Enhancements.
