installation disk images

   Mac OS X: the name of the startup script itself must match the
   name of the subdirectory it's located in. Changed MySQL->MySQLCOM 
   in the Do-pkg script and renamed the file in BK. (Thanks to Bryan
   McCormack for reporting this)

   /Library/StartupItems/MySQL to /Library/StartupItems/MySQLCOM
   to avoid a name space collision with the MySQL Startup Item shipped
   with Mac OS X Server, updated the MySQLStartupItem PKG version
   number to reflect the change.

   "-apple-darwin7.3.0-powerpc") - this is needed as we now will provide
   Mac OS X 10.2.x and Mac OS X 10.3.x PGKs (and it's more in line of
   how we name all other packages)

   for Mac OS X and add it to the installation Disk Image.

   already existing "--skip-dmg" (per Monty request)
 - Fixed handling of license files

   packaging
 - enclosed some variables in quotes for safeguarding
 - add a license file (GPL or MySQLEULA) to the package so it will be
   displayed during installation (needs to be tested)

 - moved helper functions from Bootstrap script to logger.pm 

   distribution
 - added Bootstrap, logger.pm and Do-pkg to Build-tools:
   Bootstrap is used to build the source distribution for the binary builds
   logger.pm includes some helper functions
   Do-pkg converts a binary distribution into a Mac OS X PKG (still needs
   some polishing)
