Fix DatabaseHandler to support ListActivity.

I learned how to actually use Android SQLite this week in class.  This work is based off of class examples and assignments.  It successfully enables you to add, update, and save recipes (just their names).

I highly recommend using these barebone activities and layouts as a foundation to merge your activity work and layouts in, rather than us trying to adapt the DatabaseConnector to a patchwork of activities and layouts.

My next task would be to support all `Recipe` fields, support `Recipe` deletion, and prime the database with `Recipes` and `Ingredients`.
