Now 5 digests for free

I've upgraded all free accounts from having a maximum of 3 digests to a maximum of 5 digests. Enjoy! Other upgrades include an increase from 10 max feeds per digest to 12 on the Basic package, and the Pro package moves up to 150 digests and 100 feeds per digest max.

I guess the next step is to move the automated upgrade system into place, and let you guys upgrade! Watch this space..
