Bug #764909

Clarify the math of the Tech Leakage option

This is my first issue report, so please tell me what I'm doing wrong.

In Research Options, the tooltip (and game.ruleset comment) for Tech Leakage should clarify the strength of the setting; that the game currently applies a discount of a flat percentage equal to the ratio of the players that satisfy the criteria.

It is currently unclear what setting Tech_Leakage=True actually does to the tech cost.

Bonus points: That value should itself be tweakable. This would involve coming back and reading this parameter in the base_cost multiplier in the tech_leakage section of common/research.c.

Related to Revision 3986 (16 years ago, ironically, this was explicitly spelled out)

Attached patch makes the improvement to help of the 'techleak' server setting. The setting is only available in S3_0 and later, so retargeting this to 3.0.0.
