make universal true for exercise

Exercises can either be universal (there will be several of these,
they are the general exercises that are known - bench, squat, etc.)
and user-specific. The user-specific one is so Users can enter
their own variation of the exercise and track that without polluting
the global exercise pool. For example not everyone needs to have
an option of close-grip half-depth incline bench. (or do they?)
