Checked the Turkish validators translations.
I removed comma from **trans-unit=51** because in Turkish we **GENERALLY** dont use comma just before conjunctions.
In addition, since the word **_slug_** is not understandable for Turkish speakers and there is no exact translation, I replaced **_slug_** word with the a Turkish word (**_Alan adı_**) which is more understandable.
