Slower Science Longer Eras

Modifies science output, research costs, beaker yields and much more, to make each era last longer and to prevent you just steamrolling through the research as the game progresses.

Other modifications include reducing unit training costs to allow for slightly larger armies between each era, and enables wealth production in cities immediately to prevent some AI derpiness early game when they have nothing left to build in cities (and to allow you to get some early gold instead of just producing and deleting units over and over in the very early stages).

Should be compatible with any other mods (including new technology mods such as "Beyond the Future") as it is a SQL based mod. It will also work with any gamespeed you choose as most things are altered by percentage amounts rather than hard amounts - but definitely works best with marathon!

* Research costs of all techs incremented by 15% more per tier (+15% for ancient era techs, +30% for classical, +45% for medieval etc.).
* Research base multiplier for each gamespeed increased by 25% (on marathon, this is a 400% increase instead of default 300%).
* Research costs no longer get reduced by huge amounts in later eras - instead they gradually increase, up to +200% at postmodern.
* Unit production base multiplier decreased by 33% (on marathon, this reduces production costs for units to roughly 200% instead of default 300%).
* All buildings and wonders that give beakers or increase research output have had (almost) all science-related outputs halved - for example university grants +1 beaker for jungle tiles, observatory grants +25% science not +50% etc.
* Great scientist research boosts give half the amount of instant beakers towards current research.
* Great scientist academy tile improvement beaker output halved.
* "Wealth" production in cities is enabled with the agriculture tech - the free tech everybody starts with.
* Brave New World only: Research cost increase per-city set to 5% for all map sizes (by default, this is reduced to 2.5% for Huge maps)
