Adds preliminary support for CJK languages

See #10.

This adds support for the two cases that `parse` should handle for Chinese.


@eliasdorneles , sorry for the delay.

What @Allactaga  said is correct, November is written literally as "10+1-month". My `.replace('101', 11)` was just a hack to get it to show as `11月` instead of `101月`, which is insufficient for converting years and days correctly.

Typically when you see a date written in all Chinese characters it is used in very formal writing/documents - so it's rarer, but the function should still support it.

Since we are only dealing with the numbers from 0 to 31, it might make sense to just enumerate all of them in a `dict`. The function can then do the conversion directly.

Let me know what you think of the code (edited down for brevity) below, and if it seems fine, I can submit a new pull request. Thanks!
