Summary: Add an option to return latent time entities. This can be used when one is pretty certain that the input contains a datetime.

When using speech recognition, we might see things like "six thirty six a m" or
"ten thirty p m".
Also fixed the argument order of `timeOfDayAMPM` to be more idiomatic.

Summary:
* Locales support for the library, following `<Lang>_<Region>` with ISO 639-1 code for `<Lang>` and ISO 3166-1 alpha-2 code for `<Region>` (#33)
* `Locale` opaque type (composite of `Lang` and `Region`) with `makeLocale` smart constructor to only allow valid `(Lang, Region)` combinations
* API: `Context`'s `lang` parameter has been replaced by `locale`, with optional `Region` and backward compatibility.
* `Rules/<Lang>.hs` exposes
- `langRules`: cross-locale rules for `<Lang>`, from `<Dimension>/<Lang>/Rules.hs`
- `localeRules`: locale-specific rules, from `<Dimension>/<Lang>/<Region>/Rules.hs`
- `defaultRules`: `langRules` + specific rules from select locales to ensure backward-compatibility
* Corpus, tests & classifiers
- 1 classifier per locale, with default classifier (`<Lang>_XX`) when no locale provided (backward-compatible)
- Default classifiers are built on existing corpus
- Locale classifiers are built on
- `<Dimension>/<Lang>/Corpus.hs` exposes a common `corpus` to all locales of `<Lang>`
- `<Dimension>/<Lang>/<Region>/Corpus.hs` exposes `allExamples`: a list of examples specific to the locale (following `<Dimension>/<Lang>/<Region>/Rules.hs`).
- Locale classifiers use the language corpus extended with the locale examples as training set.
- Locale examples need to use the same `Context` (i.e. reference time) as the language corpus.
- For backward compatibility, `<Dimension>/<Lang>/Corpus.hs` can expose also `defaultCorpus`, which is `corpus` augmented with specific examples. This is controlled by `getDefaultCorpusForLang` in `Duckling.Ranking.Generate`.
- Tests run against each classifier to make sure runtime works as expected.
* MM/DD (en_US) vs DD/MM (en_GB) example to illustrate

Summary:
- Fixes#89. "<number> <number>" would parse as Time if in the right range.
- Applied same rule for all languages. Note that for Italian and Polish, I updated "<hour> <minute>" tests to be in the form "at <hour> <minute>".
- Replaced `liftM2` with more generic `and|or . sequence [f1, f2, ...]`.

Summary:
We can detect certain kinds of contradictions sooner,
producing a token with an unresolvable Predicate is wasteful.
For a text like:
```
"Demain apres midi 14h 15 h 16h vendredi 14 a 15h"
```
it could produce 7000 tokens with empty predicates.
After this change it produces none and we get a 4x improvement in
time and 6x improvement in allocations.
Note I only covered `ruleIntersect*` here. I need to do this for
other instances as well.

No need to reinvent the wheel when `dependent-sum` has what we need. I re-export `Some(..)` from `Duckling.Dimensions.Types` to cut down on import bloat.
