Improved licensing model

hello2morrow switches to yearly licenses

We decided to make our licensing model more flexible. The most important change is that we changed from perpetual licenses to rented licenses. Rental periods range from 1 month to 3 years. While the license price still depends on the project size, the sizing steps are now linear. This lowers the entry barrier for medium size projects up to 1 MLOC significantly.

Existing customers with perpetual licenses are not affected by the change.
