Csharp fxcop

Hi Josh - Here are some changes I made to support our new (in Coverity 6.5) FxCop/MSVSCA analysis. It has the option to automatically search the workspace for DLL/EXE files with matching PDBs, and automatically run the Microsoft analysis. You may also specify them individually. At a glance this diff looks surprisingly (I did this on a version a few revs back) clean so maybe this is gtg? - James
