Permission to use 'fuzzy wuzzy' external library

Purpose

Make the 'search modules' feature better for the user by implementing fuzzy sort, so that minor misspelling still returns the closest modules that can be found in the NUSMods API. E.g. 'search Machien Learning' will return modules with keywords 'Machine Learning' instead of no modules being returned.
