I took a look at the energy field routines while eating lunch, so here's a new build in just 2 days rather that a few weeks
- each station type (Horizontal and Vertical) has its own Energy Field design (2 flickered shapes for each design)
- last Energy Field flickered shape kept track for each station, so Energy Field will always alternate between its 2 shapes regardless of Station flicker rate.
- Added X-Y check to make sure energy field is onscreen before drawing it. This appears to have fixed all the drawing glitches
