Identify changes to reach 0.2.0

[SamGRosen]

Some possible ideas:

• Some configurations for databases other than sqlite3
• Make logging faster by not writing to disk/committing to database every log. We could write to disk every 100 logs or so and also at close to increase performance (need to make sure no logs are lost however).
• Generate html reports of a log

Some notes:

• If a change requires an outside library we will make a new requirements file called requirements-extra.txt . This will allow people to install diary without outside dependencies but also allow those who want the extra features to take the outside dependencies.
