Add rake task to pull tweets for all accounts

This rake task adds a core piece of functionality to the app: it populates the database with tweets for all real and fake accounts.
It clears all existing data from the Tweets table, establishes a connection with the Twitter API, and loops through all entries in the TwitterHandles table to pull user timelines for each account listed there, saving them to the Tweets table.

The task relies on the untracked '.env' file which makes the required Twitter authentication information available as an environment variable.
