you can now use dashes in the exercise name
cleaned up the viewExercise form a little and the schedule form for routines and exercises
Go button for view by muscle groups

Force a search for muscle groups. Can be used after searching via name,
which populates the exercise list with the matched exercise search
query. Since the selection can still be on "all groups" and the exercise
list still contain the prevoius search results, this button can be used
to force a search.
cleaned up the exercise modification UI and made some minor adjustments with enabling disabling, replacing radio buttons with a check box and a label
Modify Fixes

- You can now modify Exercise names without getting errors. For example
--Rename "Running" to "Running Fast" does not throw an error any more.
- On page load, the modify form gets loaded with the first exercise
selected in the view exercise form
- Changing anything in the modification form automatically updates the
view exercise form now
