Provide a way to refresh text of a report

[damithc]

When I was tweaking content of title.md and/or blurbs.md, I had to rerun the java -jar RepoSense.jar --view command every time I wanted to see how my changes appeared on the report. As my report included some big repos, this took about 5 minutes each time.

I wonder if we can provide a way to just refresh the text only e.g., java -jar RepoSense.jar --text --view that will allow a user to quickly preview the report (i.e., reuse the data generated from the previous runs but regenerate the text content from title.md and blurbs.md).
