Allow students to define all words in the text

Students should be able to highlight any word and not only translate it but also define it. This would help with 504, IEP's and ELL's. It also helps students become more independent in their vocabulary acquisition. Addtionally, when having ELL students define the high utility words it would really help them if they could just define the word in the text (in Realize) and see it in context with the defitintion.
