[Feature Request] Add definitions to the word history for download

[chrisrhughes]

Current function:
Word history shows the word, the sentence it was defined in, the source/URL it was found, and the time it was added.

Feature request:
Word history should show the word and the definition. This is what another popular extension, "Dictionary Anywhere," does. The other metadata provided is not useful for vocabulary purposes. It would also be helpful if users could choose the level of verbosity for these definitions. For example, the word and the first common definition is preferable to providing all possible definitions for the word. Being able to forgo any word-use demonstration in a sentence is also preferable.
