fix lua assertion on event argument passing

Browse Source 
When adding elements to a table, the .add() function does not behave as
expected in various cases, making it really shit and difficult to use.
Instead, we keep our own index and just add one by one. It works, and
it's easy to understand.

This may lead to indices which are nil, i.e. non-fully-sequential
tables, but I can't be asked to worry about it because that shouldn't be
an issue when we use .set() everywhere.
