Clicking on a button that is animating-out is only done by
mistake. Better make them unclickable.
Also, interrupt an out-in animation if it has been preempted.

This adds a number to the extension.

Note that for DownloadManager to keep this, the server
needs to send it a mime type it does not recognize. Right
now, it does not recognize application/json so it's okay,
but we'd do well to remove the content/type header from
the server to prevent problems.

Handling buttons directly in the preference causes large
problems of code readability and interface.  It's better to
have a class to manage the buttons and their animations
separately. This is feature-equivalent, and mostly
delegates stuff for now.

This is more readable and will help with animations going forward.

The life span of this object is actually the life span of the interface.
It should not be static.
Also, we'll have a few other things to store in there soon.

This preference is not a DialogPreference any more, as it doesn't
ever display a Dialog.

LogUnits have been annotated with the autocorrected words, but
until now this was assumed to be a single word without spaces.
But spaceless typing can result in spaces in the LogUnit label.  With this
change, the LogUnit inspects the autocorrected text to determine how many
words were inserted, and counts them accurately.

This change corrects a privacy problem, which was that if the word sampling
algorithm chose a LogUnit that actually contained multiple words, then more
than two successive words would be included in the log.

Also, theoretically, we don't want to retrieve older suggestions if
there are no results for a recorrection - that would look random.
This bug addresses this too.
