Merge remote-tracking branch 'origin/maint-0.2.2'

changes/bug6094

+  o Major bugfixes:
+
+    - Send a CRLF at the end of each STATUS_* control-port event.  A
+      change introduced in 0.2.3.16-alpha caused Tor to emit the CRLF
+      in the middle of a STATUS_* event; among other things, this
+      caused Vidalia to freeze.  Fixes bug 6094; bugfix on
+      0.2.3.16-alpha.
