Make Script Errors from Northstar Callbacks Fatal

[EladNLG]

Read Title.

Why

Because:

• Errors are incredibly confusing when non-fatal - there is no indicator that an error is happening
• The error is unknown without a try/catch block
• Errors cannot be tracked to a line, or file, and its location has to be figured out manually
• They can throw a game into an unexpected state with no indicator, confusing both players AND developers

here is the function definition for other reviewers:

SQRESULT sq_call(HSQUIRRELVM v, SQInteger params, SQBool retval, SQ-
Bool raiseerror);

code looks good, unsure if this will affect any existing mods (though if they are affected they already have an error so perhaps breaking already broken mods even more is best)
