Bug fixes

• Fixed a soft-lock that could occur when killing a ceiling sucker at exactly the same time as it sucked up Duke.
• When dying due to shooting an airlock and then respawning at a checkpoint, Duke would remain in the spinning animation. This is now fixed.
• Fixed a small visual glitch appearing during the fade-out of the intro movie.
• The credits screen shown during the attract mode loop didn't react to any key press aside from ESC, this is now fixed.
• Under certain circumstances, the main menu would respond to a keypress that happened during the intro or another menu. This is now fixed.
• Fixed visual glitches (bright lines between tiles) that could occur at certain resolutions/window sizes when using high-res replacement graphics.
• Fixed an issue that made high-resolution backdrop replacements appear as low resolution under certain circumstances.
• Fixed right side of the HUD being partially cut off at certain window sizes/resolutions.
