QInstalationValidator small fix - skipping non-existing database connections

[dmarkic]

On line 142 of QInstalationValidtor you do: $db = QApplication::$Database[$i];

Without checking if this connection is defined or not. I suggest you add a line before that:

if (!isset(QApplication::$Database[$i]))

continue;

I have some databases defined, but not in correct order, (eg, 2 and 6), so this fails with fatal error on line 148 with $db->Connect as $db is not an object.

I've attached the patch.

Patch for QInstalationValidator against 1.1.1 distribution.

Looks safe to me. Check it in. :)
