* Changed bootman.S to use the BIOS provided drive to stage load itself, as well

as when the boot menu entry has a 0 BIOS drive. This allows the boot loader to
  be installed on any drive.
* Implemented BootDrive class, and changed LegacyBootMenu the way it should
  work now. Installing the boot menu should now work again, and the first time
  while installing Haiku.
* Removed MakeArray.cpp - we already have such a tool in our repository.
* Build BootLoader.h automatically during the build process - the only
  disadvantage is that you can only build it on x86 now (but other systems
  don't use this boot loader, anyway).
* In general, the BootManager is prepared to handle different kinds of boot
  menus; one only needs to write a class BootMenu implementation for this to
  work - and have the possibility to choose between different menus, if there
  are more than one per platform/partitioning system.
* Renamed quite a few methods.
* Automatic whitespace cleanup.
