Subject: implement swank:default-directory and swank:set-default-directory
X-Git-Url: http://christophe.rhodes.io/gitweb/?p=swankr.git;a=commitdiff_plain;h=843d2b6fcbc794e06e2fb5e9b2842175ffcb7ec5

implement swank:default-directory and swank:set-default-directory

It was surprisingly hard to intuit getwd() and setwd(), what with
apropos("dir") and apropos("cwd") failing.  Nevertheless, they exist
and function, so use them for the interface (but not slimefun)
functions.
