// The local array autocompleter. Used when you'd prefer to
// inject an array of autocompletion options into the page, rather
// than sending out Ajax queries, which can be quite slow sometimes.
//
// The constructor takes four parameters. The first two are, as usual,
// the id of the monitored textbox, and id of the autocompletion menu.
// The third is the array you want to autocomplete from, and the fourth
// is the options block.
//
// Extra local autocompletion options:
// - choices - How many autocompletion choices to offer
//
// - partialSearch - If false, the autocompleter will match entered
// text only at the beginning of strings in the
// autocomplete array. Defaults to true, which will
// match text at the beginning of any *word* in the
// strings in the autocomplete array. If you want to
// search anywhere in the string, additionally set
// the option fullSearch to true (default: off).
//
// - fullSsearch - Search anywhere in autocomplete array strings.
//
// - partialChars - How many characters to enter before triggering
// a partial match (unlike minChars, which defines
// how many characters are required to do any match
// at all). Defaults to 2.
//
// - ignoreCase - Whether to ignore case when autocompleting.
// Defaults to true.
//
// It's possible to pass in a custom function as the 'selector'
// option, if you prefer to write your own autocompletion logic.
// In that case, the other options above will not apply unless
// you support them.

There are a few features that I didn't implement:
* IE workarounds. I wasn't really sure what the existing code did so I just commented it out.
* Fade in/out effects.
----
Attached is a little patch that makes the autocomplete.js above work for me in Firefox; it also makes key up/down work better (works around the lack of cleanWhitespace) and removes the workaround for MochiKit 1.1.
It would be great if keys could work in MSIE as well, but I'm not sure how to enable that.
Oh, and the problem with overlapping input-elements in MSIE is annoying as well, I'm not sure to reenable the workaround for that.
