(Optionally) hide current split time until a configurable number of seconds before the split is over

LiveSplit doesn't show the diff time until (I believe) the segment is nearing the gold split time.

I'm thinking of adding an option to have full control over the columns, like in LiveSplit (See #134). This would include configuring the Update Trigger field, which should let you do this.
