[EVENTVWR]

- Attempt to speed up loading and displaying logs in EnumEventsThread:

- Rewriting the code fix an infinite loop that could happen under low memory conditions (this potentially speeds things up quite a lot).

- Remove ListView subclassing - sorry Hermès but not only it keeps constantly redrawing under Windows but also adds too much overhead.

- Don't read the event log records one by one but in chunks of roughly 0x7ffff bytes (maximum size allowed).

- Use poor man's "caching" of the event user name (optimizing/caching rest of the stuff in the loop didn't yield any significant speed up).

Result: Loading ~40000 records under Win7 went from 4.5 minutes to 65 seconds. Show less
