Improvements in science display (#8990)

* Displaying science overflow

* The amount of science from research agreement notification

* Check tech progress at the start of a turn

* Fixed exception

* Better remainingScienceToTech calculation

* Multiple technologies can be researched in one turn

* Small improvements
