*
*  Plugin disables weapon drop on death (shiled also supported, bomb excluded).
*
*  Engine and fakemeta module required.
*
*  CVAR amx_noweapdrop_ondeath (0: OFF, 1: ON, default: 1) disables/enables the plugin
*
*  Versions:
*    0.2   - solved possible server crash issues
*            maxents num uses global int now
*    0.1.2 - added entity validity extra check
*    0.1.1 - added shield support
*    0.1   - initial release
