Instead of setting 100% width on the message, causing inappropriate wrapping of the button text. Removed the nbsp in the Try Again text

I do not like how the alert component is hyper specialized for two distinct use cases. It would be much better to refactor the alerts so that the alerter can just fill the alert with whatever they want. But I do not feel comfortable making that refactor because I know ben and evelyn have gone back and forth about these alerts.

made alert messages translation-ready
updated project saver hoc
default alerts to COLOR_ORANGE

got tests working

made neutral button color

Removing highlight when hovering over alert close button after one closes, other minor styling fixes.

Moving click handling to alert component from container in order to handle index correctly.  Removed AlertsComponent and added new AlertComponent.
