now installer can disallow to install from a remote location

 - at the moment the implementation is windows only
 - in some cases it is problematically to install big installers from a
   remote location: if the connection is lost -> crash
 - the installer itself can have the flag DependsOnLocalInstallerBinary in the config.xml file
 - or a component can request that installer.setDependsOnLocalInstallerBinary()
