BootManager: improved layouting

Addresses #15418 without completely solving it.
At least for font sizes >= 11 points it works mostly. Buttons are
no longer cut off, though the summary page showing all partitions
is taller than necessary for > 3 partitions, esp. for smaller font
sizes.

Views aren't vertically centered at least.

Use B_USE_WINDOW_SPACING

Use B_USE_WINDOW_SPACING as inset from contents to window border.
Some whitespace cleanup.

BootManager: add a permanent "Quit" button.

As suggested on the mailing list by stippi and korli, it is important to
let the users know they can quit at any time, and it's sometimes the
only thing they can do.

More catalog-related cleanup.

* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h

The renamed macros require adjustments to all external applications
using catalogs.

* 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.

* Work in progress of being able to choose the drive to install the menu to.
Note, the BootManager might not work right now, anymore.

* Renamed its signature to BootManager as well.
