Add ability to make states public

[JackWilb]

Closes #149

Waiting on some frontend changes here and on some testing

[JackWilb]

• Need to add Switch from material ui to creation screen with "public" label
• Need to update requests for PUT and POST state to use new params

[haihan-lin]

• Made the changes.
• fixed the alerts (I think?). There should be success/failure alert at the bottom of the interface upon clicking confirm.
• The button also disables if there is no input for state name.

Things I noticed:

• no timeout for snack bar (can we add one so it doesn't just persist until closed?
• making state cleared the states list (on internal server error, works on success)

My TODOs:

• Test that public states are available to all
• Test that private states are not available to all

the snacker timeout is a minute. maybe 5 seconds instead?
