lmd_stashzone functionality

I noticed that when using a stash spawns via lmd_stashspawnpoint, it does not show up in the console when the /stash command is used. Also, force sense or binoculars are useless with custom stashzones.

lmd_stashspawnpoint

Keys
----
allowSense - 1: Allows force sense/binoculars to pick up the stash with an effect or the binocular beeping
StashFX - The fxfile to run when force sense is used on the stash

lmd_stashzone

Keys

showstashes - 1: All stashes under this zone will show up in the /stash command once spawned
