Subject: add `swank:apropos-list-for-emacs`
X-Git-Url: http://christophe.rhodes.io/gitweb/?p=swankr.git;a=commitdiff_plain;h=df701650ca9a83709e81e75c423ac3cc882cb246

add `swank:apropos-list-for-emacs`

and also `swank:describe-definition-for-emacs`, helping to make it
useful.  It's still a bit weird with the confusion between name of
thing, name of help file, and so on (and also because
describe-definition-for-emacs must return a definition kind from a
restricted set defined in base slime) but it's basically working.
