Tweaks based on player feedback — Lichenvale Steam update #141405

This patch contains various improvements based on player feedback: - Added a green lantern at the graveyard in first level to signal that there is a lever - Platforms leading to Blessed Anhk in second level had been expanded - Increased the attack wind-up time for various enemies - Bosses no longer reset to full health when player dies, instead they will keep their current health unless its is below 50% for Boogieman or 66% for Knightmare Lord, at which point they will reset at those values. - Fixed an issue where save files were not written to a disk.
