Summary:
Support custom dimensions
Had to move the definition of `Dimension` from `Duckling.Dimensions.Types` to `Duckling.Types` to avoid cyclic imports between these two modules.
A sample custom dimension is in `exe/CustomDimensionExample.hs`.
Limitations of custom dimensions:
- All rules for a custom dimension must be in the same module with the definition of the custom dimension. Otherwise there will be cyclic imports, because the definition of the dimension and the rules refer to each other.
- The custom dimension must be specified when using `parse`, since there's no way to get all the existing custom dimensions.

Summary:
Adding more support for "natural" language compound ordinals:
"twenty nine", "twentynine", and "twenty–nine".
These tend to come up in text that has been transcribed from audio, informal user input, and more formal printed material respectively.

Hi, in this pr:
* Added time dimension to Arabic language, thanks to Hussein-Dahir & Yazeed-Obaid for writing time corpus.
* Fixed some bugs in numeral & ordinals and added more test cases for them.
Also, I don't really understand why do we use classifiers in time dimension?

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* API: `Context`'s `lang` parameter has been replaced by `locale`, with optional `Region` and backward compatibility.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:
There are problems in the ordinal recognition for Swedish. The most severe one is that all the numbers above 15 are actually Danish, not Swedish. Apart from that digits and digits followed by a dot are considered ordinals.
This pull request fixes this and also adds support for ordinals up to 100. The structure of the code is similar to in the ordinal recognition in English. Tests are also updated, both the ordinal tests and the time tests where incorrect ordinals were used.
