Add the simplest java.util.logging.SimpleFormatter to formatsDirectory

[AddictArts]

I would think this would be a good default to have.

java.util.logging.SimpleFormatter

The current regex defaults use lowercase "info", "error", etc. Maybe it is an older logger style, but these are uppercase for the simple case.

Hi @AddictArts!

As far as I understand, this formatter allows to customize the log event a lot (e.g. put the severity level in the arbitrary place inside the log event). So it's not possible to cover all variations through the single regex.
