Sheldon Rampton's sandbox: Twitter delete

This extends the Twitter module for Drupal by adding a mechanism that deletes old tweets from the Drupal database before the Twitter module refreshes a user timeline. This can be useful as a way of making sure that a user's deleted tweets don't continue to appear on Twitter blocks on the Drupal site.

WARNING: Since this module deletes all old tweets prior to refreshing the user timeline, it can wipe out a lot of old tweets when it runs. This happens to be fine for my use case, but if it isn't what you want to happen on your website, please don't install this module! Essentially it means that instead of the Twitter module building a growing archive of tweets from selected Twitter accounts, the Twitter module merely serves as a caching mechanism for storing recent tweets so that Twitter doesn't have to be queried every time your website displays a block of tweets. For my particular use case, this is exactly what I want. If users who visit my website want to see older tweets, they can simply go to Twitter and find them there. However, that may not be your use case, so please use this module carefully and understand what it does before you use it.

Also, please note that this module requires the following patch to the Twitter module, or else it won't do anything:
