Revert "Make sure we get a stacktrace for as many lua errors as possible"

This reverts commit 362ef5f6ced862daa4733034810d0b07e2ad5d89.

Stack tracebacks couldn't be generated in LuaError::LuaError anyway and this
caused a second, empty traceback in most cases.  In cases where there wasn't
annother traceback the stack had already unwound and the traceback was empty.
Remove lua_State parameter from LuaError::LuaError
Add more informative error messages for inventory and item method errors

Parallax mapping with slope information.
Overriding normal maps.
Fix serializing of signed numbers in serializeStructToString
Fix "ghost stacks" created when a player clicks an item on the ground:

think an object is there, therefore leading to item duplication. This code
therefore sets the itemstring to '' after the object is picked up to avoid
such issues
