Previously, a logunit was considered a word only if it was all letters.  This is important for
tracking bigrams correctly.

Now, a logunit must have only at least one letter.  The dictionary check is still performed,
and punctuation, etc. still comes in as separate LogUnits.  But a word can contain a space,
which helps set up for logging words where spaces are inserted automatically, and other situations
in which text is committed with an additional space tacked onto the end.

password data collection was too "sticky"; the next field wouldn't be collected either.

Upload using an intent service rather than just a thread.  More robust in case the keyboard
is closed and the upload hasn't finished yet.

- Captures complete motion data for all words in an n-gram.
- Also filters n-grams properly; if any word in the n-gram is not
  in the dictionary, it is not included.
- Simplify ResearchLog to not require explicit state
- Added LogBuffer class MainLogBuffer class to allow n-gram-level decisions
  about privacy.
- Moved LogUnit out from ResearchLogger

Move many ResearchLogger data collection points to RichInputConnection.
By collecting data here, developers do not have to remember to keep the
ResearchLog consistent with calls to the RichInputConnection.

In addition, some unnecessary log points were removed, and the ResearchLogger
is now independent of LatinImeLogger.
