Add default spacing for Layouts (#5614)

Browse Source 
* 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.
