[isabelle-dev] Future of ProofGeneral

[Makarius]

The old things are now wrapped-up in the new way as Isabelle components:

http://www4.in.tum.de/~wenzelm/test/website/dist/contrib/ProofGeneral-3.7.1.1.tar.gz
http://www4.in.tum.de/~wenzelm/test/website/dist/contrib/ProofGeneral-4.1.tar.gz

This means the slightly odd "choosefrom" heuristics in 
Isabelle/etc/settings can be discontinued eventually. People hooked on the 
repository need to init one of the above components in the usual way in 
their etc/settings or etc/components
