[BtS MODCOMP] Resource Tech Research Modifier Mod

I take no credit for creating this mod. This is the work of TheLopez. All
I did was port it over to Beyond the Sword.

This mod adds the tags to enable faster research of a technology if the
civilization has access to particular bonuses. So for instance in the sample
included CIV4BonusInfos.XML file, copper is now revealed by Mining instead of
Bronze Working and if the civilization has access to copper then researching
Bronze Working will be 95% faster. To achieve this the following XML tag
snippet was added to the copper definition in CIV4BonusInfos.XML following the <TechObsolete> tag.

If you want to use this mod component in your mod I have tried to make things
as easy as possible for you. In the SDK files I have added:
/*** RESOURCE TECH RESEARCH MODIFIER MOD 27 July 2007 by Grave START ***/
/*** RESOURCE TECH RESEARCH MODIFIER MOD 27 July 2007 by Grave END ***/
in all of the places where changes were made.
