[web] Blame view

- `CodeChecker store` command will store blame information for every
source files if the project which was analyzed is a git repository.
- The GUI will have an option on the report detail view to show
blame information alongside the source file.
- Hovering the mouse over a blame line, commit details will be shown
in a pop-up window. Clicking on the hash will try to jump-to the remote
url of the repository and show the commit which related to a blame line.
- Add new test cases.
