Added command description.
Added 'build_clib' and 'build_temp' options (where to put C libraries and where to put temporary compiler by-products, ie. object files). Moved the call to 'check_library_list()' from 'run()' to 'finalize_options()' -- that way, if we're going to crash we do so earlier, and we guarantee that the library list is valid before we do anything (not just run). Disallow directory separators in library names -- the compiled library always goes right in 'build_clib'. Added 'get_library_names()', so the "build_ext" command knows what libraries to link every extension with.
