PATCH: completion for zstyle

[Peter Stephenson <pws@pwstephenson.fsnet.co.uk>]

Here's some completion support for zstyle.  In the first argument it will
complete only :completion: or :zftp:; for the second all the standard styles;
for the third, it knows about most completable values for the various
styles (and knows whether they are specific to :completion:* or :zftp:*).
Goodness knows if I've used contexts and tags in a consistent fashion
within _zstyle itself.

It's possible that styles and tags will need moving out to _styles and,
say, _complete_tags, but it's not yet necessary.

It also adds some .distfiles stuff I missed before.
