adblockplusopera: Fix loading race condition

When starting Opera, a race condition will sometimes occur. It can most easily be reproduced by installing several other extensions (as much as 18 for me), but I suspect it's happening even with only ABP installed on less powerful machines.

There are more setTimeout() calls in that file, I think you should replace all
of them for consistency.

lib/adblockplus_compat.js:318: window.setTimeout(invokeCallback);
setTimeout(..., 0)?

Issues addressed. There's still one setTimeout call left, but that has a delay,
so it's apparently not just for async execution.

You're right. This only worked because the readyState is never "complete" at
this point (at least for me).

LGTM

Please note however that additional parameters in runAsync are deprecated - that
functionality pre-dates Function.bind() and should be replaced by it eventually.
