API table.setn

Obsolete; throws an error if called.
 table.setn(table, n)
==Arguments==
:; table:Table - The table to be changed.
:; n: - New table size.
==Details==
* Lua 5.0 had no length operator; instead, the size of arrays could be acquired through table.getn(t), which returned t.n if it that key was set. This function would explicitly set that key.
* In WoW, this function throws a "'setn' is obsolete" error when called.
