Bump version: 2.0.1 → 2.0.2

Bump version: 2.0.0 → 2.0.1

Update release date of v2.0.0

This is 1.0

After being way to long in development
I decided to release the first version of FlaskBB.
With this release I have set myself a goal to make more
releases of FlaskBB which will hopefully accelerate the development of
FlaskBB (which stagnated a bit).
