[EVENTVWR]

[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.
