Currently ResearchLog requires a full dictionary to perform privacy-related checks.
This makes testing difficult. This change allows a fake dictionary to be used instead.

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.

Previously, a logbuffer only held an n-gram. Data went in and out of it, FIFO, until privacy
conditions were met (i.e. data not collected too frequently), and then an n-gram was saved.
E.g., if n=2, and only 10% of data is collected, then 18 words went through the logbuffer before
it captured the next 2 words.
However, if a user then went back and edited the n-gram, these edits were not captured.
This change changes the logbuffer size to temporarily hold data about words that are not recorded,
so that if the user backs up over them, the edits to an n-gram that we do eventually capture are
stored. If the example above, instead of a logbuffer holding 2 words, it holds 20. The system
waits until all the words not needed for the n-gram have been gathered (i.e. the buffer is full),
so the user has adequate time to edit, before shifting out the n-gram. The buffer is still flushed
when the user closes the IME. See the comment for MainLogBuffer for an explanation.

The IS_EXPERIMENTAL_DEBUG flag gives a single place to turn off all debugging flags that might be
set and to also enforce privacy controls. Currently only used in the research package.

- broaden OUTPUT_WHOLE_BUFFER to log not just the buffer at the end, but everything along the
way. This should only be set when the user is aware that logging is on, e.g. in a user test.

multi-space logging should look like single-space logging, missing a few minor log statements

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.

- 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
