Big changes coming!

I've been busy this week-end with the project. First of all, I've made the system compile to a shared library. This should make the system more robust under Win32, and should pave the way to support for ``freezing'' the system with freewrap (previously, we couldn't, because we had a custom interpreter, but the only reason for that was historical).

In addition, I'm in the process of reworking the persistence system. It's already much better architecture-wise, so I just need to go and factor out common code into classes to slim down the executable's size.

Compiling is still too hard, though, so I'll very soon supply a new Win32 executable archive and start distributing Linux executable.

If anyone with autoconf experience is interested, I'd be happy to hear from you...
