qzdoom-gpl/src/g_hexen/a_clericholy.cpp
Christoph Oelckers f1602882c8 - added a no-parameter Spawn function for inventory items that never show on the map, because the coordinate and replacement parameters will always be 0 for them.
- started converting g_hexen.

Most importantly this removes CHolyWeave as it is just a specialized version of A_Weave with far more convoluted use of parameters.
