This also adds some optional debug code to detect more easily possible
future occurrences of the same problem.

The new behavior is as follows:
- If the word in the dictionary is not fully lower case, then the
exact case is required to match.
- If the word in the dictionary is fully lower case, then any of
the following patterns match:
  - fully lower case
  - only the first char capitalized
  - all caps
Any other capitalization is rejected.

This is probably what people want. If you type a name in all lower
case, it should be marked as a typo, but if you type a word with a
capital for emphasis or just because it's the start of the sentence,
it should match a lower case word in the dictionary. If you have
a spurious capital letter in the middle of a word because of a typo,
it should be marked as such.

Accents are not affected, and should not be. An accented letter
is a different letter and a missing accent should be reported.
We should maybe consider again for some common transpositions
like the "ue" digraph for German, which is now considered a typo,
but will suggest the correct diacritics as the first suggestion.

This change refactors the dictionary selection code so that the
cached dictionary files list and the settings tests are more
cleanly separated.
This will also help with future refactorings that will test for
the presence of the main dictionary and insert the fall back if
it's not supplied by the dictionary pack.

Now that the dictionary pack can return several files, it's better
to handle IO exceptions for each file rather than globally. This
also will help with next implementation steps.

The dictionaries and proximities are not thread-safe. In order to
be able to check spelling in parallel, make a dictionary pool to
call upon when a spelling check is necessary.

Until the dictionary itself is re-entrant, unfortunately we have
to synchronize accesses to it.
