This change records the number of words entered in every LogUnit.
This metric is helpful for determining how much multi-word gestures
and spaceless tapping is used.

This change renames containsCorrection to avoid confusion with
CorrectionInfo, and to better clarify its meaning.

JsonWriter requires that its clients pass it only a single top-level object.
The existing implementation tries to make code cleaner by having mJsonWriter
never be null, and instead use a global static "NULL_JSON_WRITER" that just
discards data.  But because JsonWriter complains if more than one top-level
object is passed, making this a global object does not work.  This change
instead copes with mJsonWriter being null.

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.

This code is cluttering readability and getting in the way
of future updates.
Future updates will make it much easier to debug and to
test this code, so this needs to disappear.

The method in LogUnit for publishing a LogStatement to a JsonWriter doesn't
depend on anything in the LogUnit.

- Add support for replaying log files to the ResearchLogger.  This will let
  users preview data that they choose to upload.
- When the user explicitly requests that the system record their action, it
  will record everything up to, and including, the motion involved in shutting
  off the recording.  This change also removes the stop-recording motion
  commands.

Heuristic to determine whether a word was a typo correction or a complete
replacement by examining a correction to see if it falls within the list of
suggested words of the original.

Previously, words were pushed out of a LogBuffer one at a time.  The receiving code had to keep
state to know whether a n-gram was safe to log.  This patch looks at the entire n-gram and makes a
single decision based on it alone.

If the user makes a correction to a word, this is now explicitly indicated
in the logUnit.

Log statements are now recorded with a timestamp.  This is important for filtering out statements
not part of words that are sampled when spaces are inserted automatically.
