Custom Timespan in Production tabs

TL;DR (20 second video):

Why: It's often very useful to know production stats over more precise time windows, so you can check if production is working as intended "since you switched it on" instead of having to wait for the full (10) hour window.

For other purposes (like "How much ammo was spent during this biter fight (or spaceship flight)") it can be impossible to get the right stats. (my video is not the greatest example of a specific situation where it's useful (has my science been good for the last 25 hours?), it was simply intended to showcase the issue/implementation)

In general, the gap between 1h and 10h is very large, altough peoples desired additions vary wildly. A customizable timeframe therefore would be splendid (and will finally put all the different requests in this thread to rest :p )
