[#2001] Extract c-authorship-file component from views/c-authorship (#…

…2096)

contributors. 

Let us break down frontend files in a logical manner, starting with
extracting c-authorship-file from views/c-authorship.

This would provide a starting point towards further refactoring of the
frontend.
