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.

The keys' blinking that mentioned in the bug is caused by switching
keyboard layout resets the animation's alpha value to opaque but the
animation is still running and changing the alpha value
asynchronously.

I think that switching keyboard layout between alphabet and symbols
doesn't imply that the user stops typing. So the keyboard view should
continue typing state timer to keep animations' alpha values changing
and never reset the value.

KeyDetector should use the distance from the hit box to detect the
key.

I tracked all the calls to the constructor, and the passed
list is never null. It's also final, so it's safe.

All calls to this methods are made with an actual String. No sense
beating ourselves with an interface stick.
