Match library syntax with R7RS

[GoogleCodeExporter]

Owl modules are first class objects though, but this might actually be a good 
thing. The REPL could for example keep a *modules* variable to which the 
defined modules are added, instead of binding a variable according to the name. 
This might actually make some future module bookkeeping tasks easier than if 
they float freely in random variables.

Added library handling to repl, and just added rename to exports.
Missing within libraries: import quantifiers, include(-ci), cond-expand

Missing from toplevel: import, which currently works with old modules.

Plan: 
 - finish library support
 - rename old import
 - migrate all owl modules to new library system
   + replaces also old ,require and ,load, which could now be at toplevel as in library declarations (?) 
 - remove old module support
 - push also debugging data, type (record or otherwise), serialization (related) other special library-specific things to the new libraries, instead of module and db thread as was done before.

added import quantifiers, most of cond-expand, no including yet

Added include (sans -ci, which is related to another issue), and *library-dirs* 
which is used to decide where to try to load libraries from. Not closing yet 
because I forgot to add cond-expand logic...

Had an unexpected moment of computer time, so added the remaining logic to 
cond-expand. All tests pass and apart from toplevel includes and include-ci, 
which are somewhat different issues, everything is in place. Closing this and 
starting migration to new libraries soonish.
