Remove enum elaborated type specifier

...from orientation params. Elaborated type specifiers are not needed
for C++ code and removing them makes doxygen happy. Verified working
on both gcc2h and gcc4h builds.

Make archiving hooks protected in layout classes.

Furthermore,
* remove a stray blank line in Layout.cpp
* make BLayoutItem::SetLayout() private, as it should have been

Override a bunch of methods in layout related classes for FBC stability.

* Especially made sure to override archiving methods, since these are called rarely, so the cost is very minimal
* Otherwise, the closer a class is to a base class, the more likely I was to give it all the overrides.

Forbid copying and assignment in layout classes.
Specifically in:
* BAbstractLayout
* BAbstractLayoutItem
* BGridLayout
* BGridView
* BGroupLayout
* BGroupView
* BLayout
* BSplitView
* BTwoDimensionalLayout

Add FBC padding to all (I think..) of the visible Layout related classes.

Add Perform() methods to all the layout-related classes that needed them.

* Added ItemAt() method that accepts column and row.

Add default spacing for Layouts (#5614)
* introduce B_USE_DEFAULT_SPACING, which works somewhat like B_SIZE_UNSET and B_ALIGN_HORIZONTAL_UNSET
* introduce static float BControlLook::ComposeItemSpacing(float spacing), which checks uses be_control_look->DefaultItemSpacing().
* modify layouts to use BControlLook::ComposeItemSpacing() in SetInsets and SetSpacing methods.
* default insets are still 0, 0, 0, 0, but can be set to default spacing by passing B_USE_DEFAULT_SPACING
* I've found two regressions, patches incoming, please report others on #5614.

Update BLayout::ItemAdded() and BLayout::ItemRemoved() to take an int32 index parameter, and ItemAdded() to return a bool indicating success or failure. Update BLayout::AddItem() to take the result of ItemAdded() into account. Also update BLayout::AllUnarchived() to take this into account. In either situation, if ItemAdded() returns false, the item does not get added to the layout. Removed various TODOs about code that could be removed once this change was made. In BSplitLayout, an item's LayoutData was lazy-initialized, but would always be created during ItemAdded(). Now we create the LayoutData explicitly, so that we can catch failed memory allocations. Closes #5524.

Patch by Alex Wilson:
* Implemented archiving/unarchiving support.
* Coding style cleanup (some more by myself).

Finished unifying the Interface Kit headers:
* Fixed copyrights (puncuation and capitalization, removed authors from
headers)
* Updated indentation style
* Unified pointer/reference style
* Re-ordered some methods for better grouping where it could be done
(abd adopted source accordingly)
* Small coding style fixes here and there

No functional change intended.
