Review Kanji Lists and Add Missing Definitions to the Dictionary

[SethClydesdale]

I've noticed that words learned in compounds in the Kanji Lists are not present in the dictionary. Since I want to provide a comprehensive list of all (or at least 90%) of words learned in Genki, we'll have to go over all the kanji lists and add in definitions that are missing. The list below will show our progress.

• [x] Lesson 1 (Hiragana)
• [x] Lesson 2 (Katakana)
• [x] Lesson 3
• [x] Lesson 4
• [x] Lesson 5

Small Update Once all the kanji list definitions have been filled in, the dictionary should be completed and cover most of the words encountered in Genki. After this, I intend to add a new feature to practice and workbook exercises to make up for their lack of furigana; a quick dictionary search that'll be embedded on the page and accessible via a non-intrusive button. While it's recommended to memorize the vocabulary in a lesson before tackling the grammar exercises, there's always a chance one may forget, so having a tool on hand to quickly look up words should prove helpful.

All definitions should now be filled in. If anyone notices any incorrect definitions, feel free to open a new issue or pull request to let me know.
