[PATCH] Add sqlite and sqlite3 completion.

["Benjamin R. Haskell" <zsh@benizi.com>]

From: "Benjamin R. Haskell" <zsh@benizi.com>

This adds completion for the sqlite and sqlite3 commands.

I posted the first version of this in workers:28923, asking about limiting the
filenames.  Bart responded in workers:28924 that filename filtering was the job
of the file-patterns style.  Because of that (and because SQLite files often
have no .sqlite-identifying extension), I punted on it: the options that take
filenames (-init, and the positional argument for the SQLite db file) just use
_files.

This version also handles the differences I observed in sqlite/sqlite3 handling
(sqlite3 allows "--option", has --csv as an output format, and has a few more
options).
