[PD] MIDI rt / clock questions and fixes

[Toshinori Ohkouchi]

Once upon a time I made thats two object for my live performance.
But at that time midiclikin did not work well cause of jitter.
And keep compatibility with MAX on Macintosh, 
They were voided.

I dont have Linux so it was NT only.

Sorry my strange English.
