Sentence detection should be able to handle Armenian puntuation

[IreneStr]

The Armenian language has some punctuation marks that are similar to many other languages, but are used for a different purpose (example: ':' is used as full stop). It also has is own unique punctuation marks (example: ' ՜' is used as exclamation mark). The sentence detection should be able to use the correct ones as a sentence terminator.

For posterity: We can only solve this by looking at the locale and changing behaviour for it.
