root/main/trunk/greenstone3/web/WEB-INF/classes/interface_basic2_gd.properties

translations were all in interface_basic_xx.properties files. I wrote a script to split these files into the 4 main interface files, default, default2, basic, basic2, and put the right strings in each. Done based on key only. No check whether values for the same keys in different files antually matched. They will all need to be checked by translators.
