Make the partial inventory loss configurable regarding the death damage source

[CraftedMods]

Especially interesting for PvE.

Notes:

• Notion was initiated by a player at Ilu Ambar who suggested to prevent any inventory losses due to suffocation as that cause can sometimes be a result of erroneous respawning.
• It will be worthwhile to create a dedicated module in Lembas that manages death events, independent of the PvP Mode mod. This module would enable custom setting of respawning conditions, including location and effects upon respawning, much like the DeathControl plugin. Compatibility with the LOTRmod must ofc be ensured.
