New Pharo-Launcher package for Mac and Windows

Hi,

I've just updated the 2 installers for mac and windows.

http://files.pharo.org/platform/launcher/Pharo_0.2.4.dmg
http://files.pharo.org/platform/launcher/pharo_installer-0.2.4.exe

- the windows installer should have the PharoV30.sources file that was
  missing

- both installers now install the most recent Pharo launcher
