v3.0.0 - PostgreSQL, FSRS Scheduling, Multi-facet reviews

What's New?

• First review with "multi-faceted" reviews. Example: Failing a speaking exam does not change stats for a listening exam. This is more inline with goals from the whitepaper.
• PostgreSQL. Migrating from SQLite had to happen at some point. I decided to do it now before we get too many users.
• FSRS. Once I hit the 1,800 card mark, it became obvious that SM-2 would not scale to the level I wanted. I swapped out SM-2 for FSRS vis femto-fsrs.

v2.3.0 - Final v2 release

The next release will be v3, which will use a new scheduling algorithm and database (PostgreSQL).

Since I had only a small handful of v2 beta users, I have decided to not do an automatic data migration. Please contact me if you are using v2 and need help upgrading.
