Since there's 2 sets of stylesheets in the feature, a generic "stylesheets" name
isn't very descriptive. The "entering" stylesheets are the ones parsed from the
response headers, might be more clear if instead of "transition_stylesheets" you
renamed these to "entering_stylesheets". Same with the function
addStylesheetToTransition.

lg2m with those changes.
