Title: Add keystrokes per day plot

This pull request add a "keystrokes per day plot" to the main screen. In summary the changes contained are:

- Add `getKeystrokesPerDay` to `YVBDataManager`.
- Add CorePlot.
- Update FMDB.

I ended up settling for a scatter plot, but I also tried a bar chart, see here:
