Updated for 1.37.1

Tweaked the Ideas Code to force AI Iberia to choose Exploration 2nd. Taking expansion for AI Castile/Spain remains the same for their 4th idea group.

This will be temporary unless it works well in order to prevent a TOO late Colonialism spawn and for Mesoamerican Players not to get screwed over.

Updated the mod to 1.37 for the latest two DLCs.
Rebalanced England and France (to hopefully fix the error where England was selecting Exploration first constantly for some)
Restored the Expansion Ideas growth temporarily to see if it makes a difference.

Changed AI Exploration limitation from 1495 to 1485.
Changed AI Expansion limitation from 1580 to 1560.
Recent 1.36 update caused issues such as countries not doing colonialism until after 1520 severely delaying everybody. Scandinavian region has been included in the list of countries likely to colonize after a certain point.
