Dump %TRUN in the log when RejMaxQ occurs

When the maximum number of simultaneously running tasks occurs (default 10) no new tasks will be started. The log will show RejMaxQ. Troubleshooting would be much easier if the log would automatically contain the contents of %TRUN at that moment.

Also the toast that notifies the user of the RejMaxQ event is easy to miss. The rejected tasks can cause confusing misconfiguration later on. It is confusing to the user, cause their setup will misbehave, without them having seen the cause, leading to the user troubleshooting in the wrong place. My proposal is to make the RejMaxQ event toast dismissable with a button instead of automatically.
