Better server checks in network.php
|Reported by:||nacin||Owned by:|
network.php makes careful double-checks (literally) for mod_rewrite in step 1, but nothing in step 2 when it actually presents the rules.
We should be able to detect mod_rewrite in step 2. If they're not running Apache at all, they probably don't need the Apache rules.
Additionally, we need IIS detection and support in both steps.
