Make danger check view changes (#391)

Make danger check view changes

Add a check that if a file with @Preview or @LargeHeightPreview
in it is changed, then the corresponding build file includes
the showkase processor.

Also change the check that prompts about screenshots to use
the same @Preview logic instead of checking for "/layout" in
the path which doesn't work with compose.

Also add missing showkase processors
