* added nogenvers target to opensim.build - sets version to 0.0.0.1
* extracted core_build target
* FIX : csc gets confused over System.Xml ref - should be System.Xml.dll as there is a System.Xml file in same dir.
* Added OpenGrid.Framework project for great justice.
* Added LoginService as base class for LoginServer (GF)
* FIX: Plugins default.build now creates target dir, otherwise it fails.
* Added VERSION file to source control - it really should be circumvented as well.
