DCC cleanups - half rewrite. New features: file names with spaces work

properly, you can have multiple dcc chats with same people (or more
useful, same nick in different ircnets), /DCC CHAT|GET|RESUME with no
arguments accepts the last request, notifies if dcc request was sent to
channel, warns about connecting to lowports, /SET dcc_autoget_lowports
specifies if autogetting should work with lowports, complains of
invalid dcc ctcps instead of ignoring. And fixed /SET dcc_autorename
OFF which didn't work before.
