Fixup some layout stuff
Fixup some layout stuff

- NEVER use BRect in constructors when using layout
- NEVER use B_FOLLOW_*, either

The tab and scroll view show ok now, but the outline list view needs to
get the proper size. I suggest using BColumnListView instead, it will
save you lots of headaches later on if you want to do an outline list
(BOutlineListView is kept only for R5 compatibility. Its API is bad).
