Added message display with word scores coloring
Added message display with word scores coloring

In analyze.py, display the messages on one line by stripping newlines.
Also show the words that affected the score with a respective color in
front of it.

Best way to run this is:
$ python analyze.py < commit_comments.json | less -SR
This makes less not wrap lines and show the colors correctly.

Later on with real classifiers we can disable/remove this display since
it will probably not be needed then.
