xF1 Unmaintained Slow query logger 1.3.1

• Fix 'undefined index file' when handling the stack trace of eval()'ed code

• Add "Track stack traces for queries" option (default disabled)
  • On the debug output page, displays a stack trace under the explain table.

• Fix error when reporting a slow query.

Now reports slow transactions.

• May get confused with nested transactions.
• May not capture all transactions.
• May invalidate assumptions if using a non-default/custom profiler

• Allow slow query threshold to be less than 1 second

• Allow slow query threshold to be configured from AdminCP
