The calculator I always wanted

[vanLudwig]

I pushed out RC1 to beta testers. I expect this to be the build that will be released to the public; if you encounter any problems, I need to know ASAP.

Unlike the BETAs, this build has licensing enforced. When the app starts up, you will be prompted to begin a free trial of the monthly service, or purchase a lifetime subscription. For everyone that has been helping me beta test, send me a private message and I will give you a code for a free lifetime subscription.
