[PlanetCCRMA] updated: common music, added: midishare-player

[Fernando Pablo Lopez-Lezcano]

Hi, a couple of erratas from yesterday's release of the CM/CLM/CMN
Common Lisp based world...
* added midishare-player packages. I could have sworn they were in the
  repository already! But they were not. Sorry. 
* updated Common Music (CM) to 2.4.2-2. The packages now have the proper
  requires for midishare and midishare-player.
