Use a bounded fifo buffer for the log events and update LoggerPanel
periodically instead of directly

The LoggerPanel gets every LogEvent added in the AWT thread. This can lead to
contention of the AWT event queue, which renders the UI unusable.

The attached patch passes the LogEvents into a bounded fifo buffer, that is
used periodically to update the LoggerPanel. This takes a lot of stress from
the AWT event queue.
