Implemented subfeature defaults
feature.jam -
* subfeatures acquired a subfeature attribute
* improved error reporting
* eliminated some unused code
* simplified, improved commenting in, and fixed bugs in minimize
property.jam -
* added missing "symmetric" label on toolset and variant in tests
msvc.jam -
* version number is now defaulted, so I can have msvc-7.1 and
msvc-6 configured, and simply type "bjam msvc".
