[PATCH] Changes for LuaTable

this patch changes the behaviour of the LuaTable PMC.
changes have to do with the reference semantics that PMCs have, and 
LuaTables should not have.

Setting and getting a value now will set (and get) a copy of the value.

Clone() returns a reference to itself, as clone() should be used for 
register to register copying (due to the by-value semantics of Lua values)
