Make all dates relative to current simulation date

[GeorgLink]

Instead of having "April 3", the platform should show how many days from the current date that is.

We can probably have a function that calculates the difference in days and wrap all dates in that.

• [x] create offer dialog
• [ ] ... (need to add more places where the date needs changing)

somewhat fixed.. ....

the simulation still is anchored to a day, but we hide the year and use relative days where appropriate.
