Reset NTP Sponsored Image counter every 24 hours

[petemill]

Description

Currently:
After startup, we show a sponsored image on the NTP on the 2nd view and then every 4 views.

New functionality:
We should reset this count every 24 hours, after which we show a sponsored image on the NTP on the 2nd view and then every 4 views.
