LOOKS LIKE POOP BUT IT WORKS.

With this update you can now save workouts to the database and they automatically get populated on the history page. Each of the workouts can be clicked on to view a popup of the workout details.

Things that need #tobedone:
* Clean up the history cells
* Implement editing/deleting from the history page
* Clean up the 💩 dialog styling
* Integrate the predefined workouts
* Clean up the messy code (sorry😭)
