1.7.4 Project Load DSO Test

_initializeProject() in projectManagement.cs fails to load datablocks or guiProfiles when running without script files.

if( isFile( %userDatablockFile ) )
      exec( %userDatablockFile );

Needs changing to

if( isFile( %userDatablockFile ) || isFile( %userDatablockfile@".dso" ) )
      exec( %userDatablockFile );

and likewise for the %userGUIProfileFile test. This looks like an oversight, as brushes and managed datablocks already have the DSO test in place.
