Do something useful with blackhole-libs

[per-gron]

blackhole-libs is a collection of modules that are often useful when coding. It contains the implementation for some SRFIs, a couple of data structures, functions for regular expressions, base64 coding, digests, fast and simple XML<->SXML, string utilities, UUID and some more stuff.

When I made it, my intention was to make a standard library for Black Hole. But I'm not sure that it's a good idea. I would much rather focus on making it so easy to share modules and libraries of modules that no standard library is required. It might be an idea to include SRFIs, but I'm not sure about that either. Why not have a SRFI package and have lots of modules and libraries depend on that package?

Anyways, I think this hinders the adoption of Black Hole, and more importantly how easy it is to share code, because of the odd ways this kind of thing introduces dependencies.

I don't know exactly how this should be done, but I think it should be fixed. But it might not be feasible to do until we have a proper package tool.

I have now moved the SRFIs to blackhole. It's in the syntactictower branch.
