Second (and hopefully the last one) batch of bug fixes: TRex-64 v 1.0.2

Here it comes: TRex-64 v1.0.2 with the following improvements:

• Fixes in NTSC: dashboard is no longer disappearing.
• Fixes one raster shift in Y during ingame.
• Fine tuning filter settings in tunes so it sounds sort of okay on both 6581 and 8580.
• Fixed instant death bug that occurs on real hardware.
