The old code would remove caps from the first letter if
auto-capsed but that makes very little sense when the word
is camel-cased. Also, it would not correctly handle
surrogate pairs, and would require a direct reference to
LatinIME and a specific method to do the processing in an
unexpected place.

UserBigramDictionary -> UserHistoryDictionary.

Also update all methods, strings and comments, except those needed
for backward compatibility (which only include the name of the
database file).

UserBigramDictionary now assumes both functionalities. It will
be renamed to UserHistoryDictionary in a future change.

There are several reasons to do this. First, there is a lot of
duplicate code in User{Unigram,Bigram}Dictionaries that are
factored by the few lines of code in this change. Also, other
dictionaries like BinaryDictionary or ContactsDictionary all
assume both responsibilities, as should be the case
theoretically.

It is also possible to do this because previous versions don't
write any unigram data that we'd want to reuse. For even older
versions that do write data, we can't really make any sense out
of it. Bigram data however can be useful, and this allows us to
reuse it easily.

A lot of things don't really make sense in the old code.
Let's streamline it for now so that we have a cleaner interface
to work with. This is preliminary work for bug 4192129.

Also add some unit tests for an introduced and an existing method.

- Have user-history based bigrams used as soon as they are entered,
  not after 6 times.
- Limit bigram frequency to 255 (this limits the multiplier to 1.8, and
  has no effect on main dict bigrams which already have this limit)
- Some TODO resolving
