Title: Feature/elbow content

Added content to horizontal elbows. This adds the concept of stack panels which are either vertical or horizontal:

- lcars-stack-vertical
- Will stack buttons vertically. This is the same behaviour we had for *all* buttons before
- lcars-stack-horizontal-left
- lcars-stack-horizontal-right
- These two will stack horizontally, with elements floating to the left or right

Making an elbow into a stack panel allows buttons inside it to act properly
