Fix crash in Sluift DOMElementConvertor
DOMElementConvertor crashed because the stack wasn't large enough for deeper nested element trees. Calling lua_checkstack grows the stack if there's need for it. Normally Lua does this for you, but the DOMElementConverter can spend quite some time in non-Lua space. Change-Id: I23e563d49191b1db1204d2f6fa7d30e2e9d05c1f
