store volatile data in a "PluginData" subfolder

[Schnobs]

ModuleManager will rebuild it's ConfigCache whenever something changes in the Gamedata directory. It ignores folders named "PluginData" and everything inside, but any other changed file will trigger a cache rebuild.

GameData/RCSBuildAid/settings.cfg stores info like window position that is likely to change often and of no interest to MM. Yet due to the files' location it triggers a cache rebuild.

Thank you very much.
