Presentation: Updated with more points, plots
Presentation: Updated with more points, plots

- Mention interpretability
- Resolve TODO about why we don't use a regressor here, but mention its
  benefits. Perhaps we want to show a plot of the curve, but that would
  make the presentation a bit full and we've shown it during updates.
- Added plots of Passive aggressive and Linear SVC. Hopefully they are
  large enough like this.
- Mention how a small labeled data set already makes the classifier
  pretty good compared to naive word lists. Again, we have investigated
  this before, but divulging more about it in the presentation would be
  off-topic.
- Mention specific discussions in potential: e.g. security reviews,
  automated sentiment tracker, more to think about.
- Some small wording changes and whitespace changes

Only thing left is replacing the language plots. The passive aggressive
algorithm seems to have more smaller languages which it considers
negative, not sure if this is a problem so I haven't added them yet.
