BetterGraves v1.2.1

A plugin that makes dying so much less stressful.

Fixed Grave Generation bug

The grave generation previously had some issues actually confirming a grave's selected spawn location was empty. For some reason, in very niche cases the generation algorithm did not catch that the given position was already occupied.
This lead to several issues, like the grave not actually spawning. This is also believed to be the cause of the "unclaimable" graves, where when a graves spawns where another grave already resides, the contents of the former grave are replaced, effectively erasing the grave.
Although I haven't entirely confirmed this, the instance where I tested the occurrence could not be replicated with the new version.

Patch notes:

• Added additional safeguard for verifying grave locations
• Removed debug messages
• Confirmed bug also fixes grave being placed where a grave already is, overriding it
  => This might be the source of the unclaimable grave issue

[1.2.1a BUG FIX] Fixed Firework Effect is null

• Fixed a bug that lies within minecraft where setting an item to an inventory where the item is a firework with properties but no effect results in a Nullpointer exception. This is solved by adding and subsequently removing a regular effect to initialize the effects list.
