Handle edict limit Lua errors in some Sandbox dupe functions
Sandbox entity spawning adjustments
* Do not store the NPC/Vehicle table in the duplications or on the entity itself. This increases dupe sizes, and we already store the spawnname so that should be enough to link into associated lists
* Use list.GetEntry where possible, avoid copying the entire list and cleans up code
Fixed list.GetEntry erroring when used
Fixed duplicator support for HL2 entities as non admin
* Sandbox now stores the EntityName on created entities and through duplicator, like NPCs and Vehicles do
* Non admins can now duplicate HL2 entities from spawnmenu, and they call appropriate hooks
* Portal cores now duplicate properly
Added resistance-hacked combine mine to spawnmenu
